The Desert Column ' by Ion L. Idriess . First published in 1932 and this is a soft cover Centenary Edition printed in October 2017. Very very difficult to obtain any single version of this book. Of course there are two facts working in the favour of this book 1. first it's about the 5th Lighthorse and a single book version & 2 It's written by Ion L. Idriess who has found his own fame over recent years. What is this Desert Column Book ? During early WW1 Idriess joined the 5th Light Horse as a trooper. For three years he kept a diary recounting his experiences , first at Gallipoli and then in the Palestine and Sinai campaigns. He recorded in his fine writing style the realities of his war - the horrors of trench war, friendship, the bad tucker , the heat , dust , flies , boredom and most importantly the war and events which are dated. It's all here descriptions of major battles. Probably forms the best compliment history of the 5th LightHorse to the Official 5th Light Horse regiment history - which is now available click to see .
