Diary Entry - 26th June, 1918

On relieving old Lambkin at the OP in the morning became rather nervous as am told the barrage was all wrong and we bashed in our own frontline, killing two and wounding thirteen men of our own. This keeps me pretty worried all day though am pretty sure in my own head that, unless the guns which were registered on the range are wrong and we have been given false calibrations, our barrage is all right. It was a coolish day and see no movement though fire a few rounds with forward gun.
