Fort Slocum

Fort Slocum was a coastal defense fort and multi-purpose military installation located on Davids Island in , near . Named in 1896 after , a prominent commander during the known for his leadership at battles such as Antietam and Chancellorsville, the fort encompassed approximately 80 acres and served as a key harbor defense site for . The island's military history predated the fort's formal naming, with Davids Island leased by the U.S. government during the in the 1860s to establish a hospital for treating wounded soldiers, including those from the , and later housing Confederate prisoners of war. Following the war, the federal government acquired the property outright to bolster defenses alongside nearby Forts Totten and Schuyler, leading to the construction of artillery batteries, barracks, and other facilities in the 1890s. Over the course of the , Fort Slocum had evolved into a versatile training hub, hosting institutions such as the Chaplain School, the Armed Forces Information School (relocated there in 1951), Officers' Training School, and units. During , the fort functioned as a major recruitment and training center, processing thousands of soldiers before their deployment to . In , it became the nation's busiest recruitment station and a critical embarkation point for troops heading overseas. Postwar, its role shifted to Cold War-era defense, briefly serving as a U.S. facility from 1946 to 1950, with the addition of a missile control facility in 1955, before final deactivation in 1966 amid military downsizing. Since deactivation, Fort Slocum's structures have largely been demolished—93 buildings were razed between 2005 and 2009 by the U.S. Army Corps of Engineers at the request of the City of New Rochelle—leaving behind preserved remnants such as mortar pits, seawalls, a , batteries, and the . The site is eligible for listing on the as a , with archaeological significance including Native American and 19th-20th century military artifacts, and ongoing preservation efforts include documentation of 18 buildings, oral histories from over 24 veterans, and a dedicated website chronicling its legacy. Today, the island remains under local jurisdiction, with potential for future redevelopment while safeguarding its military heritage.

Location and Background

Geographical Setting

Fort Slocum was situated on Davids Island, a 78-acre landmass in Long Island Sound, approximately 3,000 feet off the southeastern coast of New Rochelle in Westchester County, New York. The island lies roughly 0.6 miles from the mainland, positioning it near the border between Westchester County and the Bronx to the south. This offshore location within the western reaches of Long Island Sound provided a strategic vantage over the approaches to New York Harbor. The island exhibits an irregular, elongated shape, stretching about 0.8 miles in length and varying in width, with terrain that rises gently from the shoreline to interior elevations of up to 50 feet. Natural features include extensive wooded areas dominated by trees and underbrush, which cover much of the interior, alongside rocky intertidal shores and pockets of sandy beaches along the perimeter. marshes and wetlands fringe portions of the coastline, forming critical habitats that support a variety of coastal , species, and . Davids Island's proximity to the urban expanse of New Rochelle, just across the narrow channel, integrated it geographically into the defensive network of the Harbor Defenses of Eastern New York, encompassing key waterways and coastal zones around the region. Historically, the island was accessible primarily by ferry service from New Rochelle's waterfront, such as from areas near Neptune Park, emphasizing its inherent isolation amid surrounding tidal waters that bolstered natural defensibility against landward approaches.

Naming and Strategic Role

Fort Slocum was officially named in 1896 after , a prominent officer during the who had died two years earlier in 1894. , born in 1827, rose to command the XII Corps in the and later led the XX Corps in the , playing a key role in major campaigns including the and the . His most notable service came in 1864 when he commanded the left wing of William T. Sherman's forces during the March to the Sea and the subsequent , contributing significantly to the 's strategy of that helped secure victory in the . Established during the Endicott Period of coastal defense modernization (1890–1910), Fort Slocum's initial strategic role was to bolster the protection of against potential naval incursions by European powers, featuring concrete emplacements for disappearing guns and mortars designed to target enemy warships from concealed positions. This era marked a shift from earlier masonry forts to more advanced, steel-reinforced batteries capable of mounting large-caliber , reflecting broader U.S. military preparations for industrialized warfare at key ports. As part of the Harbor Defenses of Eastern , Fort Slocum coordinated with adjacent installations such as Fort Schuyler to the north and Fort Totten to the south, forming a layered network to control the approaches and entrances to the harbor. These forts operated under unified command to provide overlapping fields of fire, ensuring comprehensive coverage against seaborne threats while integrating with the broader Coast Artillery Corps structure. Over time, the fort's defensive functions evolved in response to changing military priorities, transitioning from primary artillery batteries—active until around 1917—to major recruiting and training operations during both world wars, where it served as the U.S. Army's busiest depot east of the Mississippi River, processing over 100,000 enlistees in World War I alone, before its deactivation in 1966.

Early History

Civil War Era

At the onset of the in 1861, the U.S. government leased Davids Island in to establish a medical facility for treating wounded soldiers. By April 1862, the site had been transformed into De Camp General Hospital, named after Samuel G. I. De Camp, and it primarily served as a receiving for casualties from early engagements. The facility quickly became one of the Army's largest general hospitals, handling thousands of patients amid the escalating conflict. To accommodate the influx of injured troops, temporary wooden structures were rapidly constructed on the , including , pavilions, and mess halls, supplemented by tents during warmer months. These buildings featured lathed and plastered interiors for basic sanitation and were overseen by Chaffee , enabling the hospital to expand its operations efficiently. The setup allowed for systematic care, with pavilions designed to hold up to 80 patients each and tents for smaller groups of 10, reflecting the urgent adaptations made to military medical infrastructure. Key wartime events underscored the hospital's critical role; it received and treated casualties from major battles including Gettysburg in July 1863. Following Gettysburg, the facility underwent significant expansion to include a prison hospital wing for wounded Confederate soldiers and prisoners of war, eventually housing up to 5,000 such patients at its peak and contributing to the care of thousands more overall. Patient capacity estimates varied with demand, but the island's setup supported thousands of patients during intensive periods, highlighting its scale as a vital Union medical outpost. As the war concluded, De Camp General Hospital began demobilization in 1865, processing the mustering out of units such as the 17th Infantry between July and October 1866. By December 1866, the facility had fully phased out its hospital functions, leading to the initial abandonment of the temporary structures and the site's temporary disuse before subsequent military repurposing.

Post-Civil War Establishment

Following the conclusion of the , authorized the purchase of Davids Island for purposes through No. 17, approved on February 18, 1867, directing the Secretary of War to acquire the property for $38,500 in accordance with prior lease terms. The island, previously leased by the federal government since 1861 or 1862 and used as the site of DeCamp to treat wounded, was officially conveyed to the that year and designated the Davids Island Reservation. This marked the transition from a temporary medical facility to a permanent post, with the federal government assuming operation of a ferry service to Neptune Island (now City Island) for access starting in 1867. The site saw limited military activity in the years immediately following the purchase, with basic infrastructure maintenance but no major until the late 1870s. Although specific appropriations for fortifications on Davids Island were not immediately detailed in postwar budgets strained by , provided general funding for harbor defense improvements in the through acts like the June 1866 appropriation for coastal forts, which supported early efforts. A was established in and later relocated in 1887 to accommodate expanded , including permanent and officers' quarters built in the late 1880s. These developments addressed the post's role in coastal defense, though basic fortifications remained modest until later modernization. The reservation's early missions emphasized recruit training and storage, with the post reopening in 1878 as a major recruiting depot under the U.S. Army's General Recruiting Service. Commanded initially by David B. McKibbin from August 1866 to September 1868 during his recruiting duty assignment, the post hosted elements for duties amid postwar reorganization. Challenges included persistent funding shortages in the reduced postwar , limiting rapid expansion, and logistical issues with island access, which relied on operations prone to weather disruptions until incremental improvements in the 1870s.

Development and Major Periods

Late 19th Century through 1916

Following the initial post-Civil War establishment, Fort Slocum experienced substantial infrastructural development in the as part of the Endicott Program, a comprehensive initiative authorized by in 1888 to bolster U.S. seacoast fortifications against modern naval threats. This program emphasized concrete batteries, disappearing and pedestal-mounted guns, and mine defenses, replacing outdated masonry forts. At Fort Slocum, construction commenced in 1891, culminating in the completion of Battery Haskin in 1897, which housed sixteen 12-inch breechloading mortars in four pits designed for rapid-fire bombardment of approaching vessels. These mortars, with a range exceeding 7,000 yards, were supplemented by mine casemates equipped for controlling submerged explosive fields across , enhancing the fort's role in the Harbor Defenses of Eastern . Further upgrades continued into the early 20th century, with Battery Fraser (1901) and Battery Kinney (1904) adding rapid-fire capabilities through two 5-inch breechloading rifles and two 6-inch pedestal-mounted guns, respectively. These installations, protected by thick concrete revetments and earth cover, allowed for concealed firing positions while integrating electrical fire-control systems—a hallmark of Endicott-era innovations. By 1907, however, the fort's focus waned as resources shifted toward harbor defense consolidation, though the batteries remained operational until mobilizations. The engineering efforts, involving over 200 laborers at peak construction, underscored Fort Slocum's evolution from a rudimentary to a key node in national coastal strategy. The fort's personnel grew steadily, reaching a peacetime of 300 to 500 soldiers by the early 1910s, comprising Coast Artillery Corps units responsible for battery maintenance, mine operations, and basic drills. This included detachments from and elements tasked with updating fire-control networks and communications. By 1910, Fort Slocum had transitioned into a primary depot for the Eastern Department, processing enlistees from and surrounding states; temporary expansions in and facilities accommodated surges, pushing effective personnel counts above 1,000 during intensive intake periods. Key incidents marked this era of growth. In September 1905, a major fire erupted in the wooden , threatening to engulf the ; over 200 officers and enlisted men formed bucket brigades in a fierce seven-hour battle against the blaze, preventing total loss but damaging several structures and highlighting vulnerabilities in early . Recovery efforts led to reinforced . Then, in 1912, the recruit training program expanded significantly under Colonel George H. G. Gale, incorporating structured athletics, marksmanship drills, and basic familiarization for up to 500 new soldiers monthly, solidifying the fort's role as a mobilization hub ahead of global tensions.

World War I

With the ' entry into in April 1917, Fort Slocum rapidly transformed into one of the largest recruit depots and training stations in the country, serving as a critical hub for processing and preparing soldiers for deployment to . The fort handled an immense volume of new enlistees from the eastern United States, with reports indicating it processed over 100,000 soldiers annually during the peak years of 1917 and 1918, facilitating their basic training, equipping, and embarkation. By December 1917, the influx had reached such levels that approximately 15,000 recruits were managed at the site, necessitating temporary overflow housing in nearby New Rochelle. To accommodate this surge, the installation expanded with 56 temporary wooden barracks and numerous tents, underscoring its role in the massive mobilization effort. Fort Slocum's strategic location near major ports provided essential logistical support for troop shipments, coordinating with the Port of Embarkation at Hoboken and to transport processed recruits across . Key units stationed there included training detachments and replacement battalions, with the fort serving as a staging point for divisions such as the 77th Division, which drew heavily from New York draftees and passed through for final preparations before overseas service. This infrastructure enabled efficient movement, with trains and ferries linking the island to embarkation points, ensuring steady supply lines amid the war's demands. The on November 11, 1918, triggered an abrupt shift at Fort Slocum, as it became a primary center for returning troops. Units such as the 327th and 325th Regiments, along with the 53rd of the 27th , processed through the fort for discharge, reflecting its reversed role in the postwar drawdown. This rapid drastically reduced the garrison from wartime peaks of over 10,000 to a skeleton force by mid-1919, allowing the post to transition toward peacetime functions while many temporary structures were dismantled.

Interwar Period

Following demobilization, Fort Slocum faced significant challenges due to the U.S. Army's reduction in force, with a proposed in amid broader budget constraints and post-war downsizing. However, the post's ongoing role as a key recruiting depot helped avert shutdown, as it continued to process and train enlistees throughout the , maintaining a stable presence despite fluctuating personnel levels. During the 1930s, the brought federal relief efforts that bolstered the fort's infrastructure through (WPA) projects, which employed both WPA workers and Army personnel. These initiatives included the construction of three fireproof barracks known as the , four duplex officers' quarters, a six-apartment building for families, an expanded sewage system, improved roads, and new recreational facilities to support troop welfare and training. Harbor enhancements, such as seawalls, were also added to protect the island's waterfront, ensuring operational continuity for limited activities like hosting the 1920 U.S. Olympic Team for training and accommodating units. As a sub-post within the Harbor Defenses of , Fort Slocum maintained a diminished defensive function alongside primary sites like Fort Totten and Fort Schuyler, focusing on administrative support, occasional coastal defense drills, and specialized schools such as the Cooks and Bakers School, though its Endicott-era armaments had been largely removed by the interwar years. Social life for enlisted personnel centered on the new recreational amenities and service clubs, fostering morale amid the era's economic hardships and the fort's transition to peacetime roles.

World War II and Later Operations

World War II Activities

During , Fort Slocum was reactivated on , 1941, as a major reception center for new draftees and a key staging area for troops deploying to overseas theaters in and the Pacific. As one of the busiest recruitment centers in the United States, it processed tens of thousands of soldiers, serving as an induction and training hub before their embarkation from nearby ports. The facility's role intensified with the U.S. entry into the war, building on interwar infrastructure to handle the surge in personnel. To support its expanded operations, Fort Slocum incorporated additional functions such as training schools for transportation specialists, including the Atlantic Coast Officers’ Training School from 1942 to 1944. prisoners of war, following Italy's surrender in 1943, were employed as laborers on the post to aid maintenance and construction efforts. A significant milestone occurred on May 27, 1943, when the first (WAC) detachment arrived, led by Staff Sergeant Gladys "Woodie" Borkowski as drillmaster, marking an early integration of women into roles with equal rank and pay to male counterparts. In 1944, the post also became a rehabilitation center for court-martialed soldiers and hosted the creation of the "Duckworth Chant" by Private Willie Duckworth, a that standardized marching calls across the .

Postwar Era (1945-1965)

Following the end of , Fort Slocum transitioned to a demobilization center, processing returning soldiers and resulting in a sharp reduction in personnel during 1945–1946. The post faced potential closure but housed Headquarters First Air Force from 1946 to 1949. It was renamed Slocum Air Force Base in June 1949, serving without developing an airstrip; the vacated the facility in 1950. The U.S. reclaimed the facility in June 1950, renovating it for renewed operations as part of First activities. Reactivated amid the early , Fort Slocum functioned as an Armed Forces induction center, inducting personnel into service and supporting recruiting missions that integrated processing for , , and recruits during the 1950s. These efforts peaked in the mid-1950s, with the post serving as a key reception and examination point for inductees from and beyond, facilitating tens of thousands of entries annually into military service. In 1955, the fort integrated fire control for Nike Ajax Battery NY-15, enhancing its coastal defense role. From 1951 to 1962, it also housed the U.S. Chaplain School, training clergy for military roles, while the Armed Forces Information School (later redesignated the Army Information School) operated there from 1951 until 1965, focusing on public affairs and communications training. Base realignment studies in the early 1960s evaluated the post's viability, culminating in a 1963 Department of Defense announcement declaring it surplus and initiating closure proceedings, which were finalized on November 30, 1965.

Closure and Post-Military Use

Decommissioning Process

In 1963, the U.S. Department of Defense announced the closure of Fort Slocum as part of broader base realignment efforts, citing the obsolescence of its coastal defense role in the post-World War II era and the relocation of key functions, such as the Army Chaplain School, to Fort Hamilton in Brooklyn. This decision reflected shifting military priorities away from fixed coastal artillery toward more mobile and nuclear-era defenses, rendering the island's batteries and support infrastructure surplus. Operations at Fort Slocum wound down throughout 1965, with official deactivation occurring on November 30 of that year. The final evacuation took place on January 7, 1966, when the last ferry transported remaining personnel and equipment from Davids Island to the mainland, marking the end of over a century of active military use. The site, encompassing approximately 80 acres and over 90 buildings including barracks, officers' quarters, and administrative structures, was declared excess property by the U.S. Army. In December 1966, the federal government approved the transfer of unrestricted ownership to the City of for $485,000, a process that involved detailed inventories of the facilities and preliminary environmental evaluations to assess the condition of the site prior to civilian handover. The decommissioning had immediate economic repercussions for the New Rochelle community, including the loss of jobs for civilian staff who supported recruiting, maintenance, and administrative roles at the fort, contributing to local concerns over reduced federal spending and employment opportunities.

Demolition and Redevelopment Efforts

The City of New Rochelle acquired Davids Island in for $485,000 and explored initial redevelopment options, including a 1967 feasibility study by Getter-Green Associates that envisioned up to 3,500 residential units alongside commercial and recreational spaces connected by a . However, in 1968, the city sold the property to (Con Ed) for $3 million to develop a , a plan that faced strong opposition and was abandoned in 1973. Con Ed returned the island to the city in 1976 for $1. These early plans stalled due to funding shortages, investor disinterest, emerging zoning disputes over infrastructure like bridge access, and the high costs of addressing contamination from decades of use, including and potential hazardous materials in the decaying structures, which deterred progress despite the island's designation as an area in 1977. In the and , several ambitious proposals emerged but faced significant resistance, particularly from environmental groups concerned about impacts to Sound's ecosystem. Xanadu Property Associates proposed a luxury housing development in the early featuring 1,750 units, an 800-slip , and a bridge link to the mainland, but the plan was rejected in 1990 after years of community and environmental opposition citing habitat disruption and overdevelopment. Similarly, in 1994, advanced a $250 million project for high-rise towers, villas, a 1,000-slip , and extensive , alongside a competing idea from the Davids Island Development Group for a family entertainment park with water features and an amphitheater; both were withdrawn by 1996 due to fierce environmental critiques and local pushback against altering the island's natural shoreline. Earlier in the decade, a 1977 concept by Hotel Columbia for a , multiple hotels, a , and also faltered amid similar and ecological concerns, leaving the site largely undeveloped. Efforts shifted toward partial cleanup in the 2000s, with Congress appropriating $26 million in 2004—secured through the advocacy of Representative Nita Lowey—for the demolition of structures and asbestos abatement on the island. The U.S. Army Corps of Engineers initiated work in 2005, documenting and removing approximately 93 decaying buildings by 2009, including the post headquarters, chapel, and officers' quarters, while preserving select historic elements like batteries and the parade ground to mitigate costs and support potential future open-space uses. This demolition addressed about 80% of the built environment, reducing hazards but leaving behind ruins and foundations that complicated full-site redevelopment. During the 2010s, discussions focused on low-impact options like eco-tourism and an artists' colony, with the formation of a in 2010 recommending concepts such as a hotel-marina hybrid or preserved natural areas accessible by ferry. Westchester County pursued purchase attempts, including a 2001 agreement to acquire the for $6.5 million to create a public waterfront park emphasizing hiking, biking, and passive recreation, though negotiations stalled over ownership and funding details; renewed interest around 2014 echoed these eco-focused ideas but similarly failed to advance due to persistent expenses.

Current Status and Environmental Concerns

As of November 2025, Davids Island, the site of former Fort Slocum, remains uninhabited and largely undeveloped, owned by the City of New Rochelle since 1976. The island's 78 acres are overgrown with vegetation, and public access is restricted due to safety hazards from deteriorating structures and potential environmental contamination, though urban explorers occasionally access it via or small . of the site's approximately 90 buildings, completed around 2008, left behind foundations and debris that contribute to these ongoing access limitations. Environmental remediation efforts at Davids Island have focused on addressing contaminants from its military history, including asbestos-containing materials in building debris, lead and other metals in soils, and chemical residues such as polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs). The New York State Department of Environmental Conservation (NYSDEC), in coordination with the U.S. Environmental Protection Agency (EPA), initiated oversight of site investigations and cleanup proposals in 2015, selecting remedies that include excavation and off-site disposal of contaminated soils and asbestos-impacted materials. In one EPA-led removal action, 33 drums of hazardous chemical wastes were extracted from the former wastewater treatment plant area to mitigate risks from legacy storage. These efforts aim to stabilize the site but face challenges from high costs and the need to balance remediation with the island's role as a natural habitat in Long Island Sound. The island supports ecological functions typical of coastal areas in western , providing and upland habitats that benefit migratory birds and , though specific designations as a formal nature preserve have not been established. Ongoing environmental concerns include the potential for to exacerbate contaminant mobilization, prompting evaluations under local initiatives. No major has occurred since the 2010 Davids Island recommendations for phased, sustainable uses, leaving the site in a state of limited intervention as of November 2025.

Cultural and Historical Legacy

Military Traditions and "Sound Off, One, Two"

During World War II recruit training at Fort Slocum, a U.S. Army post on Davids Island, New York, drill instructors introduced innovative methods to maintain morale and synchronize marching steps among trainees, particularly during long road marches. In March 1944, Private Willie Lee Duckworth, serving in an all-Black provisional training unit, originated the "Sound Off" cadence—also known as the Duckworth Chant—while leading his platoon back from a 13-mile bivouac exercise. This simple call-and-response rhythm quickly revitalized the exhausted soldiers, fostering unity and rhythm without traditional bugle calls, and was soon endorsed by the fort's commander, Colonel Bernard Lentz, for broader use across units. The core structure of "Sound Off" consists of a repetitive counting sequence designed for easy adoption: "Sound off, one, two! Sound off, three, four! Cadence count, one, two, three, four! One, two—three, four!" Early verses added narrative flair to engage marchers, such as: "I had a good home, but I left (you're right!); Jody was there when I left (you're right!); I left my gal away out west; I thought this Army life was best; Now she's someone else's wife, and I'll be marchin' the rest of my life." Variations emerged rapidly at Fort Slocum and beyond, with 1945 V-Disc recordings by the fort's rehabilitation classes featuring a monotone delivery that evolved into more melodic forms; some early iterations substituted names like "Shorty" for "Jody" (a term for a civilian stealing a soldier's sweetheart), while later adaptations incorporated service-specific references to enhance relevance during training. As a of U.S. Army tradition, "Sound Off" promoted discipline, endurance, and camaraderie, spreading from Fort Slocum to other installations by the war's end and influencing global . Its cultural reach extended beyond the through Vaughn Monroe's 1951 recording of "Sound Off (The Duckworth Chant)," which peaked at number 3 on the , introducing the to civilian audiences. The chant also appeared in films like Battleground (), where it underscored marches, further embedding it in American . Fort Slocum's active during the war played a key role in the cadence's early dissemination, with musicians adapting Duckworth's chant into structured performances and recordings that amplified its appeal among trainees. These band-led renditions, often featured in fort assemblies, reinforced the cadence's rhythmic precision and helped bridge its use from basic training marches to ceremonial events.

Influence on Local History and Culture

Fort Slocum significantly boosted the economy of New Rochelle and Westchester County from 1867 to 1965 by serving as a major military installation that employed thousands of personnel, including recruits, soldiers, and civilian staff, particularly during peak periods like when it processed over 140,000 men between 1917 and 1919 as the largest recruiting depot east of the . The fort's operations also stimulated local and shipping industries, with regular boat services transporting personnel, supplies, and equipment from New Rochelle docks to Davids Island, enhancing maritime activity in . The fort's legacy is commemorated through local memorials and educational initiatives in New Rochelle. A plaque, originally presented by soldiers trained at Fort Slocum, was restored in 2011 and prominently displayed in City Hall to honor the site's role in . The New Rochelle Public Library has preserved this history through projects, including interviews with former personnel, and hosts periodic presentations and virtual tours on Davids Island and Fort Slocum, such as a 2020 Zoom event by the city historian. Fort Slocum has shaped regional identity in Westchester County as a symbol of military heritage, influencing local narratives and . In the 1970s, post-closure, the island hosted day camps involving institutions like Iona College (now ), fostering educational connections to the site's history through youth programs. Preservation efforts in the continue through the Davids Island Task Force, established in 2010, which advocates for historical designation and public access to honor the fort's cultural significance.

Other Uses of the Name

Fort Slocum in Washington, D.C.

Fort Slocum was constructed in the fall of 1861 as one of 68 earthwork fortifications in the , D.C., specifically in the Northeast quadrant to protect the Union capital following the . Named after Colonel John S. Slocum of the 2nd , who was mortally wounded at the , this fort is distinct from the New York installation honoring Major General . Built by the 2nd , the earthwork fort had a perimeter of 653 yards and was positioned to command key road intersections along Rock Creek Church Road. Located at the intersection of Kansas Avenue and Nicholson Street NW in what is now the Manor Park neighborhood, Fort Slocum was armed with 25 guns and mortars, including one 8-inch , two 24-pounder guns, two 24-pounder seacoast guns, four 24-pounder howitzers, seven 4.5-inch rifled cannons, six 10-pounder Parrott rifles, and three 12-pounder Napoleons. The fort was designed to accommodate around 300 troops, contributing to the broader network of defenses that encircled the city with over 20,000 soldiers garrisoned across the system. It played a supportive role in repelling Confederate threats, notably providing long-range artillery fire during Jubal A. Early's July 1864 on , which targeted nearby Fort Stevens but saw only minor engagement at Slocum itself. Following the Civil War's end, Fort Slocum was abandoned and dismantled in 1865 as part of the demobilization of Washington's fortifications. Today, the site is incorporated into , where eroded remnants of the field gun and rifle pits persist amid a forested mini-oasis, serving as a preserved green space and historical trail accessible to visitors.

Other Historical Sites Named Slocum

Several historical sites honor General Henry Warner Slocum through monuments and memorials, distinct from the primary military forts bearing his name, as these are primarily honorary tributes to his service rather than operational installations. One prominent example is the equestrian statue of Slocum at in , , at the entrance to Prospect Park, depicting the general on horseback with a raised saber, dedicated in 1905 to commemorate his leadership in the . Sculpted by Frederick MacMonnies and designed by architect , the bronze figure stands on a granite pedestal and symbolizes Slocum's role in key battles, funded by the Grand Army of the Republic. The 17-foot statue was originally placed on before being relocated to its current site in 1928. At in , a dedicated to Slocum on September 19, 1902, by the State of , marks his command of the XII Corps during the 1863 battle, located on Slocum Avenue near Stevens Knoll to highlight his defensive positions on . This granite obelisk, inscribed with details of his service, serves as a lasting recognition of his tactical contributions and is maintained as part of the park's commemorative landscape. These sites underscore Slocum's national prominence without serving active military functions.
