At 4pm the 22nd Battalion began the relief of the 23rd Battalion in the Firing Line, with a frontage of ¾ mile. In spite of considerable machine gun fire on approaches the relief was completed by 9.30pm without incident. Patrols sent out and located several enemy posts, some by presence of coughing. The enemy front line was a deep continuous trench heavily wired with listening posts in front or in the wire.
