Brigadier-General Gerald Frederic Trotter, CB, CMG, CVO, CBE, DSO (21 July 1871 – 14 June 1945) was a British Army officer and courtier.

Trotter was educated at HMS Britannia, but commissioned into the Royal Scots and transferred to the Grenadier Guards in June 1892.

In March 1900 he was badly wounded when a small foraging party, mainly of officers, including Colonels Crabbe and Codrington, was ambushed at Karee Siding; one man was killed.

[3] This episode was generally regarded as "plucky" but widely reported round the world as an example of the "over-confidence and recklessness" (in the words of the New York Tribune[4]) of British officers.

[6] Trotter was made Member of the Royal Victorian Order (MVO) in 1906, was promoted to major on 8 August 1907 and retired from the regular army on 27 July 1912, joining the Reserve of Officers of the Grenadier Guards.
