The Siege of Port Hudson occurred in 1863 when 30,000 Union Army troops surrounded the Mississippi River town of Port Hudson, Louisiana. This attack, in cooperation with the attack on Vicksburg, was intended to take the Mississippi River away from the Confederates. The 6,500 Confederate Army soldiers defending the town were able to hold off the Union offensive for 48 days. The Confederate troops surrendered once Vicksburg had fallen. Some 5,000 Union men and 700 Confederate troops were killed or wounded during the siege.

From the time the Civil War started in April 1861, both the North and South made controlling the Mississippi River a major part of their strategy. The Confederacy wanted to keep using the river to transport needed supplies; the Union wanted to stop this supply route and drive a wedge that would divide Confederate states and territories. Particularly important to the South was the stretch of the Mississippi that included the mouth of the Red River. The Red was the Confederacy's primary route for moving vital supplies between east and west: salt, cattle, and horses traveled downstream from the Trans-Mississippi West; in the opposite direction flowed men and munitions from the east.

In the spring of 1862, the Union took control of New Orleans and Memphis. To make sure it could continue to use the middle section of the river, the South fortified positions at Vicksburg, Mississippi and Port Hudson, Louisiana.

In May 1863, Union land and naval forces began a campaign they hoped would give them control of the full length of the Mississippi River. One army under Maj. Gen. Ulysses S. Grant commenced operations against the Confederacy's fortified position at Vicksburg, Mississippi, at the northern end of the stretch of the river still in Southern hands. At about the same time, another army under Maj. Gen. Nathaniel P. Banks moved against Port Hudson, which stood at the southern end. By May 23, Banks's forces, which numbered between 30,000 and 40,000 men at their strongest, had surrounded the Port Hudson defenses. Banks hoped to overrun the entrenchments quickly, then take his army northward to assist Grant at Vicksburg.

Within the Confederate fortifications at Port Hudson were approximately 6,800 men. Their commander was Maj. Gen. Franklin Gardner, a New Yorker by birth. His goals were to have his men defend their positions as long as possible in order to prevent Banks' troops from joining Grant, and to keep Confederate control of this part of the Mississippi.

On the morning of May 27, 1863, under Maj. Gen. Banks, the Union army launched ferocious assaults against the lengthy Confederate fortifications. Among the attackers were two regiments of African-American soldiers, the 1st and 3rd Louisiana Native Guards. They were the first black soldiers committed to combat in the Civil War. The attacks were uncoordinated, and the defenders easily turned them back causing heavy Northern casualties. Banks' troops made a second, similarly haphazard assault on June 14. Again they were repulsed, suffering even more dead and wounded soldiers.

These actions constituted some of the bloodiest fighting of the Civil War. The Confederates began building their defenses in 1862, and by now had an elaborate series of earthworks. One of their officers provided the following description of the line of these barriers, which, as their name suggested, were made mainly from hard_packed dirt:

For about three_quarters of a mile from the river the line crossed a broken series of ridges, plateaus and ravines, taking advantage of high ground in some places and in others extending down a steep declivity; for the next mile and a quarter it traversed Gibbon's and Slaughter's fields where a wide level plain seemed formed on purpose for a battlefield; another quarter of a mile carried it through deep and irregular gullies, and for three_quarters of a mile more it led through fields and over hills to a deep gorge, in the bosom of which lay Sandy creek.¹

The elaborate defenses they built and difficult terrain in the area assisted the Confederates in keeping this part of the Mississippi under their control. The Federals had no choice but to besiege Port Hudson to obtain access to the full length of the Mississippi.

The fighting at Port Hudson illustrated how artillery affected the conduct of a siege. The Union Army combined artillery fire with sharpshooting riflemen as it attempted to keep the defenders from getting supplies of food or other necessities; the Union Navy added their big guns to the bombardment. The Confederates responded by firing their rifles and artillery at the Union forces. Recognizing how dangerous this type of fighting could be, each side also built elaborate earthworks to protect themselves.

The siege created hardships and deprivations for both the North and South, but by early July the Confederates were in much worse shape. They had exhausted practically all of their food supplies and ammunition, and fighting and disease had greatly reduced the number of men able to defend the trenches. When Maj. Gen. Gardner learned that Vicksburg had surrendered, he realized that his situation was hopeless and that nothing could be gained by continuing. The terms of surrender were negotiated, and on July 9, 1863, the Confederates lay down their weapons, ending 48 days of continuous fighting.

The siege of Port Hudson affected the Civil War and the men who fought there in a number of ways. The surrender gave the Union control of the Mississippi River, cutting off important states such as Arkansas and Texas. Both sides suffered heavy casualties: about 5,000 Union men were killed or wounded, and an additional 4,000 fell prey to disease or sunstroke; Gardner's forces suffered around 700 casualties, several hundred of whom died of disease. And on both sides, even many of those who survived found their view of war permanently changed.
