178th (2/1st Nottinghamshire and Derbyshire) Brigade

The 178th (2/1st Nottinghamshire and Derbyshire) Brigade was an infantry brigade of the British Army raised during the First World War. It was formed as a Territorial Force duplicate of the 139th (1/1st Nottinghamshire and Derbyshire) Brigade originally from those men in the Territorial Force who had agreed, at the outbreak of war, to not serve overseas. Assigned to the 59th (2nd North Midland) Division, the brigade saw service on the Western Front. The brigade saw service at Passchendaele, Cambrai and during Operation Michael, part of the Spring Offensive.

The brigade was disbanded after the war and not reformed for the Second World War.
