Our trains arrived a few days later, after which we were all perfectly equipped.
My son accompanied me throughout the campaign and siege, and caused no anxiety either to me or to his mother, who was at home. He looked out for himself and was in every battle of the campaign. His age, then not quite thirteen, enabled him to take in all he saw, and to retain a recollection of it that would not be possible in more mature years.
When the movement from Bruinsburg commenced we were without a wagon train. The train still west of the Mississippi was carried around with proper escort, by a circuitous route from Milliken's Bend to Hard Times seventy or more miles below, and did not get up for some days after the battle of Port Gibson. My own horses, headquarters' transportation, servants, mess chest, and everything except what I had on, was with this train. General A. J. Smith happened to have an extra horse at Bruinsburg which I borrowed, with a saddle-tree without upholstering further than stirrups. I had no other for nearly a week.
It was necessary to have transportation for ammunition. Provisions could be taken from the country; but all the ammunition that can be carried on the person is soon exhausted when there is much fighting. I directed, therefore, immediately on landing that all the vehicles and draft animals, whether horses, mules, or oxen, in the vicinity should be collected and loaded to their capacity with ammunition. Quite a train was collected during the 30th, and a motley train it was. In it could be found fine carriages, loaded nearly to the top with boxes of cartridges that had been pitched in promiscuously, drawn by mules with plough, harness, straw collars, rope-lines, etc.; long-coupled wagons, with racks for carrying cotton bales, drawn by oxen, and everything that could be found in the way of transportation on a plantation, either for use or pleasure. The making out of provision returns was stopped for the time. No formalities were to retard our progress until a position was secured when the time could be spared to observe them.
It was at Port Gibson I first heard through a Southern paper of the complete success of Colonel Grierson, who was making a raid through central Mississippi. He had started from La Grange April 17th with three regiments of about 1,700 men. On the 21st he had detached Colonel Hatch with one regiment to destroy the railroad between Columbus and Macon and then return to La Grange. Hatch had a sharp fight with the enemy at Columbus and retreated along the railroad, destroying it at Okalona and Tupelo, and arriving in La Grange April 26. Grierson continued his movement with about 1,000 men, breaking the Vicksburg and Meridian railroad and the New Orleans and Jackson railroad, arriving at Baton Rouge May 2d. This raid was of great importance, for Grierson had attracted the attention of the enemy from the main movement against Vicksburg.
During the night of the 2d of May the bridge over the North Fork was repaired, and the troops commenced crossing at five the next morning. Before the leading brigade was over it was fired upon by the enemy from a commanding position; but they were soon driven off. It was evident that the enemy was covering a retreat from Grand Gulf to Vicksburg. Every commanding position from this (Grindstone) crossing to Hankinson's ferry over the Big Black was occupied by the retreating foe to delay our progress. McPherson, however, reached Hankinson's ferry before night, seized the ferry boat, and sent a detachment of his command across and several miles north on the road to Vicksburg. When the junction of the road going to Vicksburg with the road from Grand Gulf to Raymond and Jackson was reached, Logan with his division was turned to the left towards Grand Gulf. I went with him a short distance from this junction. McPherson had encountered the largest force yet met since the battle of Port Gibson and had a skirmish nearly approaching a battle; but the road Logan had taken enabled him to come up on the enemy's right flank, and they soon gave way. McPherson was ordered to hold Hankinson's ferry and the road back to Willow Springs with one division; McClernand, who was now in the rear, was to join in this as well as to guard the line back down the bayou. I did not want to take the chances of having an enemy lurking in our rear.
On the way from the junction to Grand Gulf, where the road comes into the one from Vicksburg to the same place six or seven miles out, I learned that the last of the enemy had retreated past that place on their way to Vicksburg. I left Logan to make the proper disposition of his troops for the night, while I rode into the town with an escort of about twenty cavalry. Admiral Porter had already arrived with his fleet. The enemy had abandoned his heavy guns and evacuated the place.
When I reached Grand Gulf May 3d I had not been with my baggage since the 27th of April and consequently had had no change of underclothing, no meal except such as I could pick up sometimes at other headquarters, and no tent to cover me. The first thing I did was to get a bath, borrow some fresh underclothing from one of the naval officers and get a good meal on the flag-ship. Then I wrote letters to the general-in-chief informing him of our present position, dispatches to be telegraphed from Cairo, orders to General Sullivan commanding above Vicksburg, and gave orders to all my corps commanders. About twelve o'clock at night I was through my work and started for Hankinson's ferry, arriving there before daylight. While at Grand Gulf I heard from Banks, who was on the Red River, and who said that he could not be at Port Hudson before the 10th of May and then with only 15,000 men. Up to this time my intention had been to secure Grand Gulf, as a base of supplies, detach McClernand's corps to Banks and co-operate with him in the reduction of Port Hudson.
The news from Banks forced upon me a different plan of campaign from the one intended. To wait for his co-operation would have detained me at least a month. The reinforcements would not have reached ten thousand men after deducting casualties and necessary river guards at all high points close to the river for over three hundred miles. The enemy would have strengthened his position and been reinforced by more men than Banks could have brought. I therefore determined to move independently of Banks, cut loose from my base, destroy the rebel force in rear of Vicksburg and invest or capture the city.
Grand Gulf was accordingly given up as a base and the authorities at Washington were notified. I knew well that Halleck's caution would lead him to disapprove of this course; but it was the only one that gave any chance of success. The time it would take to communicate with Washington and get a reply would be so great that I could not be interfered with until it was demonstrated whether my plan was practicable. Even Sherman, who afterwards ignored bases of supplies other than what were afforded by the country while marching through four States of the Confederacy with an army more than twice as large as mine at this time, wrote me from Hankinson's ferry, advising me of the impossibility of supplying our army over a single road. He urged me to "stop all troops till your army is partially supplied with wagons, and then act as quick as possible; for this road will be jammed, as sure as life." To this I replied: "I do not calculate upon the possibility of supplying the army with full rations from Grand Gulf. I know it will be impossible without constructing additional roads. What I do expect is to get up what rations of hard bread, coffee and salt we can, and make the country furnish the balance." We started from Bruinsburg with an average of about two days' rations, and received no more from our own supplies for some days; abundance was found in the mean time. A delay would give the enemy time to reinforce and fortify.
