Trooper Thomas Colin Campbell Patterson (known as 'Col') was the son of Matthew Campbell Patterson and Harriett Patterson of Mahakipawa, Marlborough, Blenheim.
He embarked with the Canterbury Mounted Rifles on 16 October 1914 with the Main Body. Trooper Patterson died of his wounds on 30 May 1915 in his letter Trooper McMahon recounts how he died.
"Poor 'Col.' Patterson was wounded one evening just before we were relieved by another squadron. I stayed out on the hill with him till twelve o'clock, when Father Dore came with two stretcher-bearers. Poor fellow! He died half an hour after we got him into camp."
Trooper Patterson is also buried at the Canterbury Cemetery, Anzac Cove, Gallipoli, Turkey. As far as I can gather Trooper Patterson was one of four brothers to serve in World War One, the other brothers all survived the war.
