This was titled:-
The Bullring The brutal retraining ground known as the 'Bullring' at Etaples. The troops who had returned from leave or from convalescence would be 'toughened' up here before being returned to the trenches. The picture here (and Joe's interpretation of it) shows bayonet practice on the beach. Up to 20,000 men would be drilled here at one time.

A terrific storm at Etaples, unfortunately, blew down our big tent and wrecked the scenery of this production.
Things had been very lively at the Base most of the time we were there, with aeroplane raids on the railway bridge an almost nightly occurrence for a while.
We were there when the Germans put a star shell up over St. John's Hospital and bombed it, so that there were over 360 casualties; we had given a concert there the week previously. Most of the men in the nearby camps were marched out to sleep in the wood every night, after a Canadian depot camp had been blown almost off the map with heavy bombs, which tore every tent in the place to absolute ribbons.
Etaples was not exactly the healthiest spot on earth in that summer of 1918.
