I knew a fellow who actually SAW Allenby enter Jerusalem that day.
His name was Angus Kellie and he was with the Siege Train along with his Holt tractor and his 6-inch Howitzer. He had joined up as a Gunner when the War broke out, served 6 years beginning in France and Flanders, then to Suez and actions at Gaza, Be'ersheba, Jerusalem (where he was happy not to fire a single round), Armageddon and then the dash chasing Johnny Turk all the way to Damascus and Aleppo.
Sgt. Kellie's medals were donated in his memory to the XII Manitoba Dragoons/26th Field Museum in Brandon, Manitoba, 2 years ago.
I met Sgt. Kellie when he was with the Corps of Commissionaires, working night-guard at Brandon University. I was a bit taken aback at seeing medal ribbons from the Great War being worn by a working man and we got to talking. After that, I went to bed awfully late and we would talk half the night away; I learned a LOT. Sgt. Kellie actually had considerable sympathy with the ill-equipped Turkish troops he was fighting against but he had NO respect at all for the British companies which were selling medical supplies to Turkey. In this world, he hated only three things: Camels, Fray Bentos corned beef (which he was issued every day for 6 years)..... and Field-Marshal Haig. For General Allenby he had great respect but was not sure about this "crazy little Englishman with the big nose, dressed half in uniform and half in Arab clothes", the one who was "living out in the desert with the Arabs" and "telling Allenby how to run the war". He only made the discovery that he had been close enough to touch Lawrence of Arabia after he got back to Glasgow and saw the movie.... in 1921! In addition, he was a FINE piper!
All honour to Sgt. Angus Kellie, 520 Siege Bty, R.A.
