In preparation for their forthcoming operations at the 3rd battle of Ypres (which would start on 31 July 1917), between 30 June and 2 July 1917 C Bn moved to Oosthoek Wood which is just north of the road from Poperinge and Vlamertinge. The wood gave the Bn good cover and space to operate but because the unloading ramp was outside the wood the Bn’s arrival at their Tankodrome was seen by German spotters in observation balloons.
On 4 July 1917 the Germans heavily shelled the wood for several hours. The Bn Orderly Room was hit, injuring the Adjutant and the Bde Supply Officer, who died the following day. Also hit were the workshops, the transport area, and the company lines. Five soldiers and 5 horses were killed and 3 tanks were hit.
The casualties were buried in the nearby newly constructed Gwalia Cemetery.
As a result of the shelling the Bn moved to a new camp.
