Pitzer Woods was the site of July 1st & 2nd fighting during the 1863 Battle of Gettysburg.

[1] After the CCC camp closed, Fort Indiantown Gap used Pitzer Woods in 1941 and conducted aerial reconnaissance training using the battlefield.

[2] During 1943-4, Camp Sharpe used the Pitzer Woods camp ("in a muddy hollow at the bottom of a slanting road")[3] to train soldiers for psychological operations in the European Theater of Operations.

In 1946, agricultural laborers from the Bahamas (July 16)[2] and Jamaica were housed on Seminary Ridge.

The Pitzer Woods amphitheater was constructed in the 1960s,[4] and the July 3, 1998 James Longstreet memorial was erected at the Pitzer Woods site that had been dedicated in 1941.
