Bull, who has come to command 12th R.I.R. [The Royal Irish Rifles] (in McC’s place), is a 1st R.I.F. [Princess Victoria’s (Royal Irish Fusiliers)] man. We started at 7.15 a.m. this morn and returned at 2.00 p.m., and it never ceased pouring the whole time. It’s still raining, harder than ever. Roads running water. Had a bath to-night. Washing just back; very well done.
