Tag: Fort Slocum DC

Wikipedia says: Fort Slocum was one of seven temporary earthwork forts, part of the Civil War Defenses of Washington, D.C., during the Civil War, built in the Northeast quadrant of the city after the beginning of the war by the Union Army to protect the city from the Confederate Army. From west to east, the forts were as follow: Fort Slocum, Fort Totten, Fort Slemmer, Fort Bunker Hill, Fort Saratoga, Fort Thayer and Fort Lincoln.

The fort was built by the 2nd Rhode Island Infantry. It was named after Colonel John Slocum of the 2nd Rhode Island Infantry, killed in action on July 21, 1861, at the First Battle of Bull Run (also known as the First Battle of Manassas). The fort perimeter measured 653 yards (597 m) and covered the Rock Creek Church Road (today Blair Road) and New Hampshire Avenue.

The fort contained the following equipment:

One 8-inch siege howitzer

Two 24-pounder siege guns

Two 24-pounder seacoast guns

Four 24-pounder howitzers

Seven 4.5-inch siege rifle

Six 10-pounder rifled Parrott rifles

One 10-inch siege mortar M. 1841

Two 24-pounder Coehorn mortars

The batteries were never completed on the east and west of the fort. If they had, an extra ten more guns could have been added.

The following elements garrisoned at the fort at some point during the war:

76th New York Volunteer Infantry

1st New Hampshire Heavy Artillery Volunteer Regiment

150th Ohio National Guard

14th Independent Battery Michigan Light Artillery

Pennsylvania Independent Light Artillery Battery E known as “Knapp’s Battery”

It provided support to Fort Stevens west of Fort Slocum. When the Confederate States Army attacked Fort Stevens on July 11 and July 12, 1864, Fort Slocum fired its long-range guns. During the battle, 1,500 employees of the Army Quartermaster office led by General Montgomery Meigs assisted the garrison along with 2,800 hospitalized soldiers from the nearby hospitals under the command of Colonel Francis Price.
