History of Fort Farnsworth
Fort Farnsworth was also one of 33 forts on the Virginia side of the Potomac River that made up an outer defense line for Washington DC known as the Arlington Line.
Established in 1862 as one of four redoubts in advance of Fort Lyon. After the battle at Gettysburg all four redoubts were were renamed for Union officers killed at that battle. The four newly created forts were Fort Weed, Fort Farnsworth, Fort O'Rourke and Fort Willard. Together with Fort Lyon these forts created a line across the southern approaches to the city of Alexandria.
Fort Farnsworth (originally Redoubt B of Fort Lyon (3)|Fort Lyon]]) was built by elements of the 34th Massachusetts Infantry under the direction of Captain William Bacon. The original redoubt was built with a perimeter of 255 yards enclosing one magazine, a bombproof and emplacements for 13 guns. Armament included four 24 pounders, two 12 pounder howitzers, four 4.5 inch ordnance rifles (2 vacant platforms).
A 17 May 1864 report from the Union Inspector of Artillery noted the following: "Fort Farnsworth, Major Campbell commanding.–Garrison, one company Tenth New York Heavy Artillery– 3 commissioned officers, 1 ordnance-sergeant, 128 men.
