 When the infantry advanced they were preceded by a creeping barrage (a new technique at the time) fired by the divisional artillery supported by other batteries.The attack on the right was successful, and at 05.20 the infantry on the left were reported to be in Guillemont Station, but the centre was held up by a belt of barbed wire and the barrage had to be brought back to support them.Meanwhile, the Liverpool Irish held on the village until most were killed or captured.
