|Battle of Port Gibson|
While the fighting was ranging around Chancellorsville, Virginia, U.S. Grant was still pursuing his campaign against Vicksburg, Mississippi. He had run the transports past the batteries, and used them to ferry his troops to the eastern side of the Mississippi River on April 30. They immediately began pushing inland, though they were hampered by the fact that John McClernand did not issue rations to his men. The only Confederate forces in the immediate vicinity were a few brigades under John S. Bowen. He placed his troops just south of the town of Port Gibson. The position was strong – the southerners occupied high hills overlooking brush-cocked ravines. But their position was weakened in that they had no cavalry, which was off chasing Union raiders. They didn't know exactly where the Union had crossed.
