midnight
So we go on every twenty hours . Only half our set go on duty together , as that gives room for those who remain . Two came off duty at eight this morning , four are just going on . You will go on with the two who came off this morning , at midnight . Besides their sentry work , of course every one is in Readiness to man the walls at any moment in case of alarm , and a good deal of your time can be spent at loopholes , picking off the enemy directly they show themselves . One of the party , in turn , cooks each day . Besides the fighting duty , there is any amount of fatigue work , the repairing and strengthening of the defenses , the fetching rations and drawing water for the house , in which there are over fifty women and children , the burying dead cattle , and covering blood and filth with earth .
