about five o'clock
After matching a mile or two we could see to the eastward and south , great clouds of dust rolling up above the woods , evidently made by a column in march upon the road by which , we had that morning advanced from Manassas to Centreville . We knew that Pope 's army -- or a great part of it -- was making that dust , and that Pope was hot after Jackson . We crossed Bull Run on the stone bridge and halted in the road . It was about five o'clock ; the men were weary -- most of us had loaded ourselves too heavily with the spoils of Manassas and were repenting , but few had as yet begun to throw away their booty . My increased burden bore upon me , but I had as yet held out ; in fact , the greater part of my load -- beyond weapon , and accoutrements -- consisted in food which diminished at short intervals . We could not yet expect rations . We had rested perhaps half an hour .
