Mr Patch was conscripted into the Army aged 18 and fought in the Battle of Passchendaele at Ypres in 1917 in which more than 70,000 British soldiers died.
Something he said a few years ago is worth repeating.
Why should the British government call me up and take me out to a battlefield to shoot a man I never knew, whose language I couldn’t speak? All those lives lost for a war finished over a table. Now what is the sense in that, but still we send our lads to war. In Iraq, our young men are being killed and told to kill.
