13th Field Regiment (Australia)

The 13th Field Regiment was an Australian Army artillery regiment. During World War I the unit was formed in early 1916 as the 13th Field Artillery Brigade, and fought as part of the 5th Division in Egypt, the Sinai and on the Western Front. After the war, it was re-raised as a part-time unit based in the state of South Australia. It was redesignated as the 13th Field Regiment during the early years of World War II, and following Japan's entry into the war it was mobilised and later deployed to New Guinea, where a detachment fought during the Battle of Buna–Gona in 1942–1943, returning to Australia in late 1943.

After the war, the regiment was re-formed in 1948 in South Australia and remained in existence until being disbanded in 1975.
