Sir Martin Archer-Shee CMG DSO (5 May 1873 – 6 January 1935) was a British army officer and Conservative Party politician.

He was the son of Martin Archer-Shee (1846–1913) and his wife Elizabeth Edith Dennistoun (1851–1890) (née Pell) of New York[1] who married in 1872 at Piccadilly.

[citation needed] His half-brother was George Archer-Shee, whose notable acquittal of the accusation of theft became the basis of the play The Winslow Boy by Terence Rattigan.

In 1890 he resigned from the navy in order to enter the Royal Military College Sandhurst and to become an officer in the British Army.

He served in the Second Boer War 1899–1902, where he took part in operations in Natal, including the defence of Ladysmith, then in the Transvaal from July to November 1900.

[4] In February 1902, he was wounded near Kromdraal when he captured enemy soldiers (mentioned in dispatches 25 April 1902[5]), and he was invalided home in May that year,[6] shortly before the official end of hostilities.

[1] Archer-Shee was able to use his political connections to secure the services of Edward Carson in the court case involving his half-brother, George.
