Reading about WW1

If you have to go to war, going in Summer when the enemy is very, very tired is a good idea.  Russia began to withdraw from the war after the Revolution, so Germany was able to send more troops and equipment to the Western front for a last big push. Ridley arrived in France in April 1918 when the Germans were making that last effort. Men and horses were still dying and being wounded but the horrors of the mud of Passchendaele and the miserable Ypres salient were past. In April 1918 one of Ridley's friends was listed as "Missing in action" and he was finally declared as "Killed in Action" in December 1918. The man was obliterated from the face of the earth, never being found. The routine of four days at the front line  followed by four days well behind the lines gave troops time to eat, sleep, read and send mail, sleep, sleep and sleep - and mourn the loss of fellow soldiers.

Ridley was in the Strazeele and Merris area but this map doesn't have a date on it.
