Have you read "The Desert Column" by Ion Idreiss? He served at Gallipoli and throughout the desert campaign, it's a wonderful book. Gallipoli can be seen as a setback that ultimately led to victory at Beersheba. The Light Horse was the most effective cavalry in the world.
It is fortunate that Idreiss ignored orders. They were told specifically not to keep diaries lest they be captured and give away strengths, weaknesses and tactics.
I don't think they were celebrating Gallipoli. The attack was a failure (organised by Churchill), but the withdrawal was a success (organised by an Australian officer - Lt.Col. Charles White)
His horse was a demon with an evil disposition from the ninth circle of hell. When they asked for volunteers to form the First Armoured Division at the outbreak of WWII, he jumped at the chance.
North Africa. Never fired a shot - developed Khaki Dermatitis on the ship going over and was medevac'd back to Australia. What the diggers call a "golden ticket". Couldn't stay in the Army - everything had khaki dye in it - medically discharged. Lucky me.
