From Villers-Faucon, 94th Siege Bty supported the minor operations by which Fourth Army closed up to the Hindenburg Line, followed by the Battle of Épehy and the capture of Ronssoy (18 September). The battery was then ordered into the ruins of Ronssoy, which involved hauling the guns across shell-holed country by night and cramming the guns into limited space at the west end of the ruins. The village was under constant harassing fire with gas and HE, and casualties were heavy. Getting ammunition up the terrible roads was a serious problem. From these positions the battery supported Australian Corps (with II US Corps under command) in its attack on the Hindenburg Line at the Battle of the St Quentin Canal (29 September), for which the bombardment began on 26 September. The US troops had to attempt to gain some preliminary objectives before the main attack went in. Despite some shortcomings, the Australian–US attack was a success.
