Frank Percy Crozier

Brigadier-General Frank Percy Crozier, (1 January 1879 – 31 August 1937) was a British Army officer. His first military experience was in the Second Boer War (1899–1902) and with the Royal West African Frontier Force in Nigeria. During the First World War, he commanded the 9th (Service) Battalion of the 107th (Ulster) Brigade in the Battle of the Somme, earning him the promotion to brigadier general and command of the 119th (Welsh) Brigade in the Battle of Cambrai and German spring offensive.

After the war, he briefly served as an advisor of the newly established Lithuanian Army and commander of the Auxiliary Division of the Royal Irish Constabulary at the time of the Partition of Ireland. However, he quickly became disillusioned with the conduct of the auxiliaries during the conflict. Crozier became a pacifist and published several controversial autobiographical books.

Military career Crozier was born in Bermuda into a family of military traditions. Both of his grandfathers served in the army and his father was a major in the Royal Scots Fusiliers. However, in 1908, he was forced to resign due to repeated dishonoured cheques and became bankrupt.

First World War At the outbreak of the First World War in June 1914, many of Ulster Volunteers, including Crozier, joined the British Army and formed the 36th (Ulster) Division. Crozier was appointed second in command of the 9th (Service) Battalion of the Royal Irish Rifles, 107th (Ulster) Brigade.

Civilian life Crozier unsuccessfully ran in the 1923 general election for the Labour Party in Portsmouth Central. He turned to writing and lecturing to earn a living, though unpaid bills and dishonoured cheques continued to follow him.
