The II (or 2nd) Wessex Brigade was a howitzer unit of the Royal Field Artillery in Britain's Territorial Force (TF) that was formed on the Isle of Wight in 1908. It served in India and the Middle East during World War I, one of its batteries being captured at the Siege of Kut in Mesopotamia in 1916, and another seeing active service in the Third Afghan War of 1919. Although reformed after the war, the unit was broken up in 1927.
