These siege operations lasted without intermission until early in September. On the night of June 18th, the Brigade found 30 Officers and 1000 men for the trenches, of which the Coldstream, furnished 8 Officers and 263 men; and so on, from day to day, in varying numbers, according to the requirements of the moment. It was ordered on the 21st, that “in future the proportion of Officers and men in the trenches will be one Captain and one Subaltern to every 100 men;” and also “should any part of the guard of the trenches be called upon to work, they are positively forbidden to take off their accoutrements or to go far from their arms.”[331] Commencing July 10th, the duties were found by divisions—the First, Second, and Light in the Right, the Third and the Fourth in the Left Attack,—and during that night the Battalion furnished 7 Officers and 312 men, also 21 men more as a special working party.[332] ----- Footnote 331: _First Divisional Morning Order_ , June 21st. Footnote 332: Special and other working parties and shot-loading fatigues in the trenches were frequently ordered at this time. The following, relating to the duties in the trenches, may be of interest:— _Head-quarter Memo._  , July 10th: “General Officers of divisions will be so good as to detail not less than a Brigadier-General, three Field Officers, and two Adjutants for duty in the trenches on the days that their divisions furnish the guard, Right Attack.” _Divisional Order_ , July 12th: “The troops will be told off to their places in the trenches before they leave their camp, and they will move off from the parade in front of the camp, after being so told off, at 6.15, so that they may all be in their places in the trenches and the relief completed by 8 o’clock, according to the General Order on the subject.” _Head-quarter Memo._ , July 24th: “Until further orders the guard in the trenches by night, will be 2400 men, under a General of the day with three Field Officers; of this number 600 men will work if required by the Royal Engineers, from 4 to 8 a.m., and return to their camp at 8 a.m. if it should seem prudent to the senior Officer in the trenches to dispense with them.... The remainder of the guard will furnish working parties as usual during the day, when required by the Royal Engineers.... There will be a special working party, consisting of 400 men under a Field Officer, independent of the guard of the trenches, except in case of an attack, when they will be available to be called upon by the Officer commanding in the trenches.... General Officers of divisions furnishing the guards in the trenches are to consider the remainder of their division as a support ready to reinforce the guard, with which they will proceed in case of alarm, and resume the command of the whole force in the trenches.”
