The 6th Battn S.F. relieved the 3rd Battn Worcester Regt at MAROUIL & took over the duties of mining fatigue on the 51st Divisional Front.

The 7th Battn S.F. relieved the 1st Battn Wiltshire Regt on the ROUTE DE BUTHUNE & took over the mining fatigues on the 46th Divisional Front.

The weather continues to be extremely bad & the trenches are going back. Work was continued on the BROADMARSH CRATER improving the look out posts on the lip.

It was found quite impossible to complete the trench round the base of the Crater, as the mud there was knee deep & sticky to the spade.

A mine was exploded at 10.30 p.m. on the 138th front, which was the cause of considerable shelling on the front for some little time. afterwards; particular attention being paid to BOYAU CENTRAL.
