Lord Alexander George Boteville Thynne DSO (17 February 1873 – 14 September 1918) was a British Army officer and Conservative politician.

[2] Following the outbreak of the Second Boer War in late 1899, Thynne volunteered for active service and was commissioned a lieutenant in the Imperial Yeomanry on 7 February 1900,[3] leaving Liverpool on the SS Cymric in March 1900 to serve in South Africa with the 1st (Wiltshire) company of the 1st Battalion.

He had stood unsuccessfully in the 1896 Frome by-election when his brother was elevated to the House of Lords as the 5th Marquess of Bath.

During the First World War Thynne was twice wounded in the Battle of the Somme in 1916 and awarded the Distinguished Service Order[7] and the Croix de Guerre.

[11] A further act of commemoration came with the unveiling in 1932 of a manuscript-style illuminated book of remembrance for the House of Commons, which includes a short biographical account of the life and death of Thynne.
