Tuesday 19th June 1917
The Bedfordshire Yeomanry are presently at Écurie a few miles north of Arras. Since 13th the commanding officer, Major Green, seven other officers and 199 other ranks have been transferred to XIII Corps to form 9th Pioneer Battalion along with contingents from the Royal Engineers, Royal Army Medical Corps and two other units. Altogether the Battalion has 20 officers, 597 other ranks and 36 horses and is under the command of Major Green.
They have been employed on strengthening communication trenches, including laying duckboards in the bottom of them to give a firm footing when wet weather turns the ground to mud.
