Munster Alley

The 13th spent the next few days in Albert.
On the 1st August the 13th moved to Peake Wood and on the 2nd they were back in the line at Munster Alley. They dug the Sap toward the Switch Line and strengthened the barricade. That night they went back to trenches near Contalmaison.
On the afternoon of the 4th August, the 13th prepared to assault Munster Alley.
The attack started at 9.16am after a pointless artillery barrage. The first wave of 'C' Coy was killed. Attacks up the trench and a second wave gained 60 yards before stopping at a German block.

After midnight, 'A' Coy moved through the Loop to support the attack and defend the new barricade.
