BATTLE SUMMARY

Maj. Gen. Ulysses S. Grant launched his march on Vicksburg in the Spring of 1863, starting his army south, from Milliken's Bend, on the west side of the Mississippi River. He intended to cross the river at Grand Gulf, but the Union fleet was unable to silence the Confederate big guns there. Grant then marched farther south and crossed at Bruinsburg on April 30.

Shortly after midnight, the crash of musketry shattered the stillness as the Federals stumbled upon Confederate outposts near the A.K. Shaifer house. Union troops immediately deployed for battle and artillery, which soon arrived, roared into action. A spirited skirmish ensued which lasted until 3:00 A.M. The Confederates held their ground. For the next several hours, an uneasy calm settled over the woods and scattered fields as soldiers of both armies rested on their arms. Throughout the night the Federals gathered their forces in hand and both sides prepared for the battle which they knew would come with the rising sun.

At dawn, Union troops began to move in force along the Rodney Road toward Magnolia Church. One division was sent along a connecting plantation road toward the Bruinsburg Road and the Confederate right flank. With skirmishers well in advance the Federals began a slow and deliberate advance around 5:30 a.m. The Confederates contested the thrust and the battle began in earnest.

Most of the Union forces moved along the Rodney Road toward Magnolia Church and the Confederate line held by Brig. Gen. Martin E. Green's Brigade. Heavily outnumbered and hard-pressed the Confederates gave way shortly after 10:00 A.M. The Confederates fell back a 1.5 miles.  Here the soldiers of Brig. Gen. William E. Baldwin's and Col. Francis M. Cockrell's brigades, recent arrivals on the field, established a new line between White and Irwin branches of Willow Creek. Full of fight, these men re-established the Confederate left flank.
The morning hours witnessed Green's Brigade driven from its position by the principal Federal attack. Brig. Gen. Edward D. Tracy's Alabama Brigade astride the Bruinsburg Road also experienced hard fighting. Although Tracy was killed early in the action, his brigade managed to hold its tenuous line.

It was clear, however, that unless the Confederates received heavy reinforcements they would lose the day. Brig. Gen. John S. Bowen, Confederate commander on the field, wired his superiors: "We have been engaged in a furious battle ever since daylight; losses very heavy. The men act nobly, but the odds are overpowering."   Early afternoon found the Alabamans slowly giving ground. Green's weary soldiers, having been reformed, arrived to bolster the line on the Bruinsburg Road.

Even so, late in the afternoon, the Federals advanced all along the line in superior numbers. As Union pressure built, Cockrell's Missourians unleashed a vicious counterattack near the Rodney Road which began to roll up the Union line. The 6th Missouri also counterattacked hitting the Federals near the Bruinsburg Road.All this was to no avail for the odds against them were too great. The Confederates were checked and driven back. The day was lost. At 5:30 P.M., battle-weary Confederates began to retire from the hard-fought field. The Confederates established new defensive positions at different times during the day but they could not stop the Union onslaught and left the field in the early evening.

The battle of Port Gibson cost Grant 131 killed, 719 wounded, and 25 missing out of 23,000 men engaged. This victory not only secured his position on Mississippi soil, but enabled him to launch his campaign deeper into the interior of the state. Union victory at Port Gibson forced the Confederate evacuation of Grand Gulf and would ultimately result in the fall of Vicksburg.

The Confederates suffered 60 killed, 340 wounded, and 387 missing out of 8,000 men engaged. In addition, 4 guns of the Botetourt (Virginia) Artillery were lost. The action at Port Gibson underscored Confederate inability to defend the line of the Mississippi River and to respond to amphibious operations.  The way to Vicksburg was open.
