Wet morning. Bttn parades ready to move at 9.0 am & we march to SAVY via BERLENCOURT-AMBRINES very hard march & I feel done up when I get in, having my left ankle swollen with rheumatism or something. Arrive SAVY about 2.10 pm go under canvas, very bad camp & heaps of mud. Concert given by 13 Sqdn RFC at night to 250 of our men, very good. Not much sleep, rain & wind.
