[Written above date:] Messines – Wytschaete1
Awake at 3.15 am with the mines going up2 and shaking the ground. The barrage commenced then and continued until 9 o’clock. Most intense bombardment in the world’s history. A man on the battery behind got his heart smashed with the recoil of the gun and we brought him round to the aid post. Bascombe, Driver, Lee and I in number 8 squad from 2 parade. Went up the line about 9 o’clock. Brought our first case from the Red Line3 post. German trenches absolutely knocked out of existence. A fair number of Germans dead, but not many injured. A good number of German prisoners, who carried down wounded as they came. Worked from the relay post (our old front line) to the P & O4 line most of the afternoon. The first party went down at about 9 o’clock. We stayed on for the night. Called out before midnight to go to the blue line. A long walk and we were shelled most of the way down. Had to go round to P & O trench and were shelled very heavily at the new dugout.
