Following the failed counter-attack, the Germans rotated their forces along the Morlancourt front, bringing the 107th Division into the line, while throughout 15 May the German artillery fired a heavy bombardment of the Australian lines. Minor actions continued along the line until 18 May as the 18th Battalion sought to shore up its left flank. This included a daylight raid across no man's land, during which the Australians took advantage of the heat of the day when many of the German sentries were asleep, to surprise a German position. The Australians reached their objective without a shot being fired. After the Australians threw a grenade, the remaining Germans in the trench surrendered. There was a brief exchange of fire with a neighbouring position, which was quickly overcome before the raiding party returned to their lines. A total of 22 Germans were captured in the raid. Elsewhere, in late May, the Germans launched the third major blow of their Spring Offensive, attacking the French in Third Battle of the Aisne.
