History of Fort O'Rourke
Fort O'Rourke 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 O'Rourke (originally Redoubt C of Fort Lyon) was built by elements of the 34th Massachusetts Infantry. The original redoubt was built with a perimeter of 160 yards enclosing emplacements for 16 guns. Armament included one 24 pounder, two 8" howitzers, six 20 pounder Parrott rifles (2 vacant platforms).
