These, advancing over the perfectly open ground, recaptured the trenches and gallantly held them against further attacks.

In this affair the West Yorks suffered casualties amounting approximately to 15 officers and 600 other ranks, the Sherwood Foresters also losing 12 officers and 180 other ranks.
The temporary loss of the trenches by the West Yorks exposed the trenches of the D.L.I, to enfilade machine-gun fire, from which they had considerable casualties, including Majors Mander and Robb.

This was the only serious fighting in which the Division was engaged, but a certain amount of trouble was caused by the arrival of guns from Antwerp which fired "Black Marias," and the enfilade gun and machine-gun fire to which portions of the main line lent themselves.

W.R.B.
