He was born in Ohio in 1822, and received a military education at West Point. He was a successful officer in the Mexican War, having been engaged in nearly all the battles of the war, where he manifested conspicuous bravery. Returning from Mexico, he engaged a while in farming, but with discouraging results. Evidently it was not his vocation. When the Civil War opened, Grant was employed at a small salary in his father's leather store in Galena, Illinois. He at once offered the governor his services, and was appointed a colonel of an Illinois regiment. He rose rapidly to conspicuous positions. =317. Capture of Vicksburg.=--General Grant, after defeating the Confederates at the battle of Shiloh, and driving them south to Corinth, followed them to Vicksburg. This was a stronghold from which they seemed to defy every effort to dislodge them. The city stands on a high bluff some two hundred feet above the Mississippi, and as there were heavy batteries all along the river front and on the hillsides, Grant could not attack the city with his gunboats. On the north there were miles of swamps and creeks, so that he could not approach on that side. On the east the city was heavily fortified with cannon. President Lincoln and the country expected General Grant to capture Vicksburg. What could he do? Witness his superb generalship! He first protected against cannon shot a number of gunboats and steamers by means of bales of hay, and planned to run them past eight miles of batteries one dark night in April. This movement was so perilous that officers would not order their men to go, but called for volunteers. So many were eager to go that lots were drawn for a chance. One soldier refused one hundred dollars for his place. Soon as the watchful Confederates sighted the first boat of the grim procession, they opened a deafening cannonade, and started a series of bonfires that lighted up all the miles of that voyage of death. Some of the transports were destroyed, but enough got through to answer the general's purpose. Next Grant ferried his army across the river some miles below Vicksburg, and fought and defeated General Pemberton's troops, which had moved down to meet him. Then, learning that General Johnston was coming to attack him, he marched up between the two armies. On his east side he met Johnston's army and defeated it. Thence he turned west and drove Pemberton again, and the next day routed him once more and drove his entire army into Vicksburg. Commodore Porter's gunboats now threw huge shells into the doomed city from the river and Grant's army bombarded it on the east. It was an awful siege. No building was safe. The people lived in caves dug in the sides of the hills. Food was so scarce that mules, cats, dogs, and rats were devoured. At last, after seven weeks of siege, Pemberton, on July 4, surrendered his entire army of about thirty thousand men, the largest force captured during the war.
