Major-General Frederick Hammersley, CB (21 October 1858 – 28 March 1924) was a senior British Army officer.

[6] He fought at the Siege of Khartoum in 1898, and was present during the occupation of Crete later the same year, before being deployed to South Africa in 1899 to fight in the Second Boer War.

He held a staff appointment as deputy assistant adjutant general (DAAG) in Natal, and on 20 October 1899 was severely wounded at the Battle of Talana Hill.

However, his ability to oversee such an operation was subsequently called into question, and the Dardanelles Commission openly criticised his command.

[19] On 23 August 1915, he was removed from the front-line in a state of collapse and was replaced as GOC of his division by Major General Edward Fanshawe, who had been sent from the Western Front.
