enemy's line and been
obliged to remain there for security all day, were withdrawn; and thus
ended the last assault upon Vicksburg.
CHAPTER XXXVII
SIEGE OF VICKSBURG.
I now determined upon a regular siege--to "out-camp the enemy," as it
were, and to incur no more losses. The experience of the 22d convinced
officers and men that this was best, and they went to work on the
defences and approaches with a will. With the navy holding the river,
the investment of Vicksburg was complete. As long as we could hold our
position the enemy was limited in supplies of food, men and munitions of
war to what they had on hand. These could not last always.
The crossing of troops at Bruinsburg commenced April 30th. On the 18th
of May the army was in rear of Vicksburg. On the 19th, just twenty days
after the crossing, the city was completely invested and an assault had
been made: five distinct battles (besides continuous skirmishing) had
been fought and won by the Union forces; the capital of the State had
fallen and its arsenals, military manufactories and everything useful
for military purposes had been destroyed; an average of about one
hundred and eighty miles had been marched by the troops engaged; but
five days' rations had been issued, and no forage; over six thousand
prisoners had been captured, and as many more of the enemy had been
killed or wounded; twenty-seven heavy cannon and sixty-one field-pieces
had fallen into our hands; and four hundred miles of the river, from
Vicksburg to Port Hudson, had become ours. The Union force that had
crossed the Mississippi River up to this time was less than forty-three
thousand men. One division of these, Blair's, only arrived in time to
take part in the battle of Champion's Hill, but was not engaged there;
and one brigade, Ransom's of McPherson's corps, reached the field after
the battle. The enemy had at Vicksburg, Grand Gulf, Jackson, and on the
roads between these places, over sixty thousand men. They were in their
own country, where no rear guards were necessary. The country is
admirable for defence, but difficult for the conduct of an offensive
campaign. All their troops had to be met. We were fortunate, to say
the least, in meeting them in detail: at Port Gibson seven or eight
thousand; at Raymond, five thousand; at Jackson, from eight to eleven
thousand; at Champion's Hill, twenty-five thousand; at the Big Black,
four thousand. A part of those met at Jackso
