CHAPTER XV. BACK TO PORT HUDSON.

On the 7th of May Porter relived Farragut in the guardianship of the Mississippi and its tributaries above the mouth of the Red River. This left Farragut free to withdraw his fleet so long blockading and blockaded above Port Hudson. Accordingly he gave discretionary orders to Palmer to choose his time for once more running the gauntlet, and Palmer was only watching his opportunity when he yielded to the earnest entreaty of Banks, and agreed to remain and co-operate if the General meant to go against Port Hudson.

Grover began the movement on the 14th of May; Paine followed early on the morning of the 15th, while Weitzel, still retaining Dwight, was ordered to hold Alexandria until the 17th, and then to retire to Murdock's plantation, where the east and west road along the Bayou Hauffpaur crosses the road from Alexandria to Opelousas, and there await further orders.

Besides the ordinary duty of a rear-guard, the object of this disposition of Weitzel's force was to cover the withdrawal toward Brashear of the long train of surplus wagons for which there was now no immediate need, and which would only have encumbered the proposed movement of the Corps by water. All the troops took the road by Cheneyville instead of that by Marksville, in order to conceal from the Confederates as long as possible the true direction of the movement.

Having given these orders, Banks embarked on one of the river steamboats on the evening of the 15th and transferred his headquarters to Simmes's plantation on the east bank of the Atchafalaya opposite Simmesport. Thence he proceeded down the Atchafalaya to Brashear, and so by rail to New Orleans.

Grover broke camp at Stafford's plantation on the 14th of May, and marched seventeen miles to Cheneyville; on the 15th, fourteen miles to Enterprise; on the 16th, sixteen miles to the Bayou de Glaise; and, on the morning of the 17th, twelve miles to Simmesport, and immediately began to cross on large flatboats rowed by negro boatmen. To these were presently added a little, old, slow, and very frail stern-wheel steamboat, named the Bee, which, a short time afterwards, quietly turned upside down, without any observable cause, while lying alongside the levee; then the Laurel Hill, one of the best boats in the service of the quartermaster; afterward gradually but very slowly the other steamers began to come in. Grover finished crossing on the morning of the 18th, and went into camp near the Corps headquarters.

Paine, with the 6th New York added to his command for the few remaining days of its service, followed in the footsteps of Grover. Leaving Alexandria on the morning of the 15th, Paine marched twenty miles and halted at Lecompte. On the 16th, he marched twenty-five miles to the Bayou Rouge; on the 17th, twenty miles to the Bayou de Glaise, where the Marksville road crosses it; on the 18th, seven miles to Simmesport, and on the following morning began to cross.

Before leaving Alexandria, Weitzel, on the 14th May, sent two companies of cavalry to reconnoitre a small force of the enemy said to be near Boyce's Bridge on Bayou Cotile. The Confederates were found in some force. A slight skirmish followed, with trifling loss on either side, and when, the next day, Weitzel sent the main body of the cavalry with one piece of Nims's battery, accompanied by the ram Switzerland with a detachment of 200 men of the 75th New York, the Confederates once more retired beyond Cane River.

Weitzel moved out of Alexandria at four o'clock on the morning of the 17th of May, and, lengthening his march to thirty-eight miles during the night, encamped on Murdock's plantation on the following morning. The gunboats Estrella and Arizona and the ram Switzerland stayed in the river off Alexandria until noon of the 17th to cover Weitzel's withdrawal, and then dropped down to the mouth of Red River and the head of the Atchafalaya. The Confederates slowly followed Weitzel at some distance, observing his movements, and, on the morning of the 20th, attacked his pickets. Then Bean, who commanded Weitzel's advanced guard, consisting of his own 4th Wisconsin, mounted, the 12th Connecticut, and all the cavalry, threw off the attack and pursued the Confederates nearly to Cheneyville, where Barrett, advancing too boldly after the main body had halted, was cut off, with a detachment of seventeen of his troop, and, finding himself surrounded, was forced to surrender. Barrett himself and several of his men afterwards succeeded in making their escape. The attacking party of the Confederates consisted of Lane's regiment, fresh from Texas, Waller's battalion, and a part of Sibley's brigade, with a battery of artillery.

On the morning of the 22d, Weitzel, having completed the object of his halt at Murdock's plantation, marched at a stretch the thirty-four miles to Simmesport without further molestation, and arriving there on the morning of the 23d, at once began the crossing.
