5:40pm saw a gun fight where German were hit at a 30 yard range "at the edge of the scrub". After this, the companies that were furthest out were pulled back. Brigadier Sandover ordered his "reserve company" to a hill to the south, where machine gunners and the reserve company could cover the ground from which they had withdrawn.
The 2/1st Battalion had made the planned move to the main road. They were positioned so that they could look at the "mountain road" that they had travelled.
By 6pm, there were some German infantry on the west side of Gravia. While there was still some light, there was a gun fight between the Germans and a company of the 2/1st Battalion.
There was now a change of plans. At about 6pm, General Vasey was concerned about the 2/11th Battalion's situation. He ordered 2/1st and 2/4th Battalions, with a groupof extra soldiers, to load onto trucks at 8pm, instead of a half-hour later. He also told Brigadier Sandover that he needed to hold his ground until 9pm, instead of a half-hour later.
Once the 2/1st Battalion had mostly pulled out, German infantry was shooting at the right end of the 2/11th Battalion and at a part of the 2/8th Battalion. They were on the higher ground to the right.
