The squadron would score 63 aerial victories during the war. The unit's victories came at the expense of seven killed in action, four wounded in action, two injured in accidents, and one taken prisoner of war.
Jasta 56 began at Paderborn's Geschwader School on 20 October 1917, but was not officially established until 1 January 1918. Its first personnel reported in on 9 January 1918. It was assigned to 2 Armee on the 14th; it first saw combat on 9 February 1918. The new squadron scored first blood on the 19th. On 11 April 1918, it was consolidated into Jagdgruppe 6 and moved to support 4 Armee, remaining in that posting until war's end.
