At 5.30 A.M. on September 27 there was the preliminary operation, already mentioned, which should gain the ground necessary for the jumping-off place. This was done by General Lewis' Thirtieth American Division on the right with little difficulty. It was different with the Twenty-seventh on the left. On this flank a depth of about 1100 yards had to be gained, coinciding roughly with the rearmost trenches of the Hindenburg outpost line. This task was carried out by the 106th Infantry with all three battalions in line and four tanks ahead of each battalion. The leading companies, following the barrage, reached their objectives in most cases, but were involved in desperate fighting at the points already mentioned, which were connected by cross-cuts with the main German line, from which there flowed an endless supply of reinforcements. All day attack and counter-attack followed each other, both parties fighting with great valour and enduring heavy loss. By night the 53rd American Brigade was well advanced on its right, but its left was still battling hard to reach the allotted line: 8 officers and 259 Germans had been taken in the fighting. That night the 54th Brigade (Blanding) took over the new front and lay ready for the coming battle, with the 108th Infantry on the right and the 107th on the left. On the front of the Thirtieth Division {153} the 60th Brigade (Faison) was in line, with the 119th and 120th Infantry in the van, the latter to the right, in touch with the British Ninth Corps to the south of them.
