William Frederick Cockburn

William Frederick Cockburn was commissioned in the Royal Artillery on 18 February 1880. His pre-war career was notable only for its association with heavy artillery. He was Chief Instructor in Gunnery South West Coast Defences (June 1910–May 1912) and Inspector of Royal Garrison Artillery, India (June 1912–January 1916). On his return to England he became Commandant of the Central Siege School (February–April 1916).

Cockburn went to France in April 1916 to take command of the heavy guns of I Corps. He held this position until February 1917 when he was compelled to relinquish it owing to failing eyesight.

Brigadier-General Cockburn retired from the army on 5 March 1918.
