The Division then went back for a month’s rest. The relief by the 6th Division began on the 15th, and units moved into the reserve area some miles west of Poperinghe, with Divisional Headquarters at Esquelbecque. During this time brigade groups went in turn to Calais, first the 61st, then the 60th, and then the 59th, for periods of a week or ten days each. The Division was in turn in G.H.Q. and in Corps reserve, and spent the time training and refitting. The Divisional Band was formed at this time, and Sgt. Eldridge, 11th D.L.I., was appointed Bandmaster. On the 3rd of May it played for the first time in the square at Esquelbecque. On the 5th Brig.-General the Hon. L. Butler took over command of the 60th Brigade from Brig.-General Roy. On the 12th the Divisional Artillery held a horse show, which proved a great success. The condition of the artillery horses and the excellence of their turnout evoked the admiration of the whole Corps. Organised sports, horse shows, bombing and bayonet fighting competitions were also held at this period by the brigades at Calais. The march of the 59th Brigade from Calais, on the 13th of May, was rather a severe test, and showed the state of fitness to which the men had been brought. Orders reached battalions only two to two and a half hours before the move, which began at 7 P.M. The brigade marched 16 miles that night in the rain, arriving in billets at 4 A.M. on the 14th. Starting again at 11 A.M., the troops covered another 17 miles, and got into billets between six and seven in the evening. Thus 33 miles had been done in twenty-four hours. Hardly any men fell out and the march was continued in the morning. Next day the following letter arrived from Corps Headquarters: “The Corps Commander has heard with great pleasure of the soldier-like way in which the 59th Infantry Brigade tackled the difficulties of a sudden move and a wet night march. It was only to be expected of a brigade like the 59th, but it reflects great credit, all the same, on all concerned.” During May an alteration was made in the organisation of the artillery. The Brigade Ammunition Columns disappeared, and the Divisional Ammunition Column, under Lieut.-Colonel Foster, was divided into a first échelon (Nos. 1, 2 and 3 Section), and a second échelon (No. 4 Section), the latter supplying the wants of the infantry alone. This was followed by a reorganisation of the batteries. The 92nd Brigade was to be a howitzer brigade no longer. The 91st, 92nd and 93rd Brigades were each to consist of three 18 pdr. batteries and one howitzer battery, and the 90th Brigade to consist of three 18 pdr. batteries. Each battery, as before, consisted of four guns. On the 20th of May it was arranged to work the ammunition supply from a central dump at Divisional Ammunition Column Headquarters, whence issues would be made to sections, the sections delivering to battery gun positions and to infantry brigade transport lines.
