he left of the line on the 21st, a soldier, recognizing me, said in
rather a low voice, but yet so that I heard him, "Hard tack." In a
moment the cry was taken up all along the line, "Hard tack! Hard tack!"
I told the men nearest to me that we had been engaged ever since the
arrival of the troops in building a road over which to supply them with
everything they needed. The cry was instantly changed to cheers. By
the night of the 21st all the troops had full rations issued to them.
The bread and coffee were highly appreciated.

I now determined on a second assault. Johnston was in my rear, only
fifty miles away, with an army not much inferior in numbers to the one I
had with me, and I knew he was being reinforced. There was danger of his
coming to the assistance of Pemberton, and after all he might defeat my
anticipations of capturing the garrison if, indeed, he did not prevent
the capture of the city. The immediate capture of Vicksburg would save
sending me the reinforcements which were so much wanted elsewhere, and
would set free the army under me to drive Johnston from the State. But
the first consideration of all was--the troops believed they could carry
the works in their front, and would not have worked so patiently in the
trenches if they had not been allowed to try.

The attack was ordered to commence on all parts of the line at ten
o'clock A.M. on the 22d with a furious cannonade from every battery in
position. All the corps commanders set their time by mine so that all
might open the engagement at the same minute. The attack was gallant,
and portions of each of the three corps succeeded in getting up to the
very parapets of the enemy and in planting their battle flags upon them;
but at no place were we able to enter. General McClernand reported that
he had gained the enemy's intrenchments at several points, and wanted
reinforcements. I occupied a position from which I believed I could see
as well as he what took place in his front, and I did not see the
success he reported. But his request for reinforcements being repeated
I could not ignore it, and sent him Quinby's division of the 17th corps.
Sherman and McPherson were both ordered to renew their assaults as a
diversion in favor of McClernand. This last attack only served to
increase our casualties without giving any benefit whatever. As soon as
it was dark our troops that had reached the enemy's line and been
obliged to remain there for security
