 The last @-@ ditched effort by the Germans to win the war came to a grinding halt in mid @-@ July and after that there followed a brief period of lull , during which time the Australians undertook a series of small unit actions aimed at capturing parts of the German line with limited support . These actions became known as Peaceful Penetrations and were essentially a cross between trench raids and patrolling . Their success relied heavily upon the leadership and initiative of junior commanders and the ability of soldiers to employ principles of fire and manouevre . This lull did not last long , however , as the Allies were soon ready to launch their own offensive , known as the Hundred Days Offensive , which would ultimately bring about an end to the war .
