 X Corps had greater difficulty reaching some of its final objectives ; the loss of White Château disorganised the German defenders adjacent to the south . The 41st Division easily crossed the summit and reached the rear slope of the ridge 500 yards ( 460 m ) away , which overlooked the eastern slope and <unk> valley , taking many prisoners at Denys and Ravine woods . North of the canal , the 47th Division had to capture a spoil heap 400 yards ( 370 m ) long , where several German machine @-@ gun nests had been dug in . The British attacks established a footing on the heap at great cost , due to machine @-@ gun fire from the spoil heap and others in Battle Wood further north . At 9 : 00 a.m. the infantry withdrew to allow the area to be bombarded from 2 : 30 to 6 : 55 p.m. for an attack by a reserve battalion at 7 : 00 p.m. The 23rd Division had many casualties caused by flanking machine @-@ gun fire from the spoil heap while clearing Battle Wood , which took until the evening .
