CHAPTER IX. THE TECHE.
In effect, this plan was to turn Port Hudson by way of the Atchafalaya. For the original conception, the credit must be given to Weitzel, who seems indeed to have formed a very similar scheme when he first occupied La Fourche. However, his force was, at that time, barely sufficient for the defence of the territory confided to his care. Not only was there then no particular object in moving beyond the Atchafalaya, but any advance in that direction would have exposed his little corps to disaster on account of the great facilities afforded by the numberless streams for a movement by detachments of the enemy into his rear. It was largely to prepare for an advance into Western Louisiana, as well as to defend his occupancy of La Fourche, that Butler, upon Weitzel's suggestion, had created the gunboat flotilla.
Soon after Banks took the command, Weitzel, who had opinions and the courage to enforce them, laid his ideas before his new chief. On the 18th of January, disturbed by hearing that Admiral Farragut meant to take one of the army gunboats, recently transferred to the navy, away from Berwick Bay, instead of sending more, Weitzel expressed himself strongly in a despatch to headquarters.
"With such a naval force in that bay, in co-operation with a suitable land force, the only true campaign in this section could be made. Look at the map. Berwick Bay leads into Grand Lake, Grand Lake into the Atchafalaya, the Atchafalaya into Red River. Boats drawing not more than four or five feet and in the force I mention [10 or 12], with a proper land force, could clear out the Atchafalaya, Red River, and Black River. All communications from Vicksburg and Port Hudson cross this line indicated by me. By taking it in the manner I propose, Vicksburg and Port Hudson would be a cipher to the rebels. It would be a campaign that 100,000 men could not so easily fight, and so successfully. It is an operation to which the taking of Galveston Island is a cipher and the capture of the Mobile Bay forts a nonentity."
With these views Banks was himself in accord, yet not in their entirety. The pressure of time led him to desire to avoid divergences into the Teche country. If it were possible, he wished to gain the Atchafalaya by some route at once speedier and more direct. While the explorations were in progress to discover such a route, Weitzel once more took occasion to urge his original plan. On the 15th of February, he wrote to Augur, his division commander:
"I feel it a duty which I owe you and my country to address you at this late hour in the night on the present proposed movement on Butte à la Rose and the Teche country. . . . In all honesty and candor, I do not believe the present plan to be a proper one. . . . Sibley's Texas brigade is somewhere in the Opelousas country. . . . Mouton's main body is in rear of intrenchments on Madame Meade's plantation, six miles below Centreville. If we defeat these two commands we form a junction with our forces near Vicksburg. By pursuing our success to Alexandria, we may capture General Mouton's force, and with little loss, unless it form a junction with Sibley. If it forms a junction, we will meet them near Iberia and engage them in open field, and with a proper force can defeat them. General Emory's whole division (moved to Brashear City) and my brigade can do this work. Let the light transportation, now with General Emory, and all destined for and collected by me be collected at Brashear City. Let two of the brigades be moved to and landed at Indian Bend, while the other two are crossed and attack in front. If Mouton escapes (which I think, if properly conducted, will be doubtful) we form a junction at Indian Bend. We proceed to attack and with much superior force, because I do not believe Mouton and Sibley united will exceed 6,000 men. We can defeat them, pursue our success to Alexandria and of course get Butte à la Rose; our gunboats to facilitate its fall, attacking it as they cannot accompany us farther up than Saint Martinville. I believe this to be the true and only correct plan of the campaign."
These views were unquestionably sound; they were such as might have been expected of an officer of Weitzel's skill and experience and special knowledge of the theatre of operations. Supported by the strong current of events, they were now to be carried into effect.
At the date of this despatch, Emory's division had been for several weeks near the head of the Bayou Plaquemine, with headquarters at Indian Village, endeavoring to find or force a waterway to the Atchafalaya, while Weitzel was holding his brigade in readiness to co-operate by a simultaneous movement against Taylor on the Teche. Many attempts were made by Emory to carry out the object confided to him, yet all proved failures. Bayou Sorrel, Lake Chicot, Grand River, and the Plaquemine itself, from both ends of the stream, were thoroughly explored, but only to find the bayous choked with driftwood impossible to remove, and until removed rendering the streams impassable. Two of these drifts in Bayou Sorrel were carefully examined by Captain Henry Cochen, of the 173d New York. The first he reported to be about a mile in length, "composed of one mass of logs, roots, big and small trees, etc., jammed tightly for thirty feet, the whole length of my pole." The second drift, just beyond, was found nearly as bad, and farther on lay another even worse. Moreover, a thorough reconnoissance showed the whole country, between the Mississippi and the Atchafalaya above the Plaquemine, to be impracticable at that season for all arms. After more than a month of this sort of work, Emory was called across the river to Baton Rouge to take part in the events narrated in the last chapter.
Banks returned to New Orleans on the 24th of March, and the next day ordered Grover to embark and move down the river to Donaldsonville, and thence march down the Bayou La Fourche to Thibodeaux. At the same time Emory was ordered, as soon as Grover's river transports should be released, to embark his command for Algiers, and thence move by the railway to Brashear. Meanwhile, on the 18th of March, Weitzel learned of the presence of the Queen of the West and Webb in the Atchafalaya, and as this seemed to indicate an intention to attack him, and the navy had no more light-draught gunboats to spare for his further security, to avoid having his hand forced and the game spoiled, he discreetly fell back on the 21st to the railway bridge over Bayou Boeuf, and took up a position where he was not exposed, as at Brashear, to the risk of being cut off by any sudden movement of the enemy.
On the 28th of March the Diana was sent to reconnoitre the Confederate position and strength on the lower Teche; but continuing on down the Atchafalaya, instead of returning by Grand Lake as intended, and thus running into the arms of the enemy, she fell an easy prey. The Calhoun went to her relief, but ran aground, and the Estrella had to go to the assistance of the Calhoun. Acting-Master James L. Peterson, commanding the Diana, was killed, and Lieutenant Pickering D. Allen, aide-de-camp to General Weitzel, was wounded. With the Diana there fell into the enemy's hands nearly one hundred and fifty prisoners. This gave the Confederates three rather formidable boats in the Atchafalaya and the Teche.
The movement of the troops was necessarily slow, as well by reason of the extremely limited facilities for transportation, as because of the state of the roads, but by the 8th of April every thing was well advanced, and on that day Banks moved his headquarters to Brashear. Weitzel, who had been reinforced by the siege-train, manned by the 1st Indiana heavy artillery, had already re-occupied his former front on Berwick Bay. Emory was in bivouac at Bayou Ramos, about five miles in the rear of Weitzel, and Grover at Bayou Boeuf, about four miles behind Emory. Thus the whole movement was almost completely masked from the Confederates, who from their side of the bay saw only Weitzel, and knew little or nothing of the gathering forces in his rear. So little, indeed, that Taylor, with his usual enterprise, seems to have thought this a favorable moment for attempting upon Weitzel the same operation that Weitzel had been so long meditating for the discomfiture of Taylor.
Emory marched early in the morning of the 9th of April and closed up on Weitzel, who, an hour later, about ten o'clock, began to cross. No enemy was seen save a small outpost, engaged in observing the movement. This detachment retired before Weitzel's advance, without coming to blows. Weitzel at once sent his Assistant Adjutant-General, Captain John B. Hubbard, with Perkins's and Williamson's troops of cavalry and one section of Bainbridge's battery to discover the enemy's position. The Confederates were found to be in some force in front of Pattersonville, with their cavalry pickets advanced to within a mile of Weitzel's front.
As soon as Weitzel had completed his crossing, and released the boats, Emory followed him. The four brigades bivouacked in front of the landing-place that night. The gunboats, having done the greater share of the ferriage, went back to the east bank for Grover.
Grover, who had marched from Bayou Boeuf at nine o'clock, just as Emory was arriving at Brashear, came there, in his turn, early in the afternoon. The plan had been that Grover should embark immediately, and, having his whole force on board by an early hour in the night, the boats should set out at daylight, so as to place Grover by nine o'clock on the morning of the 11th in position for the work cut out for him. With few pilots, and the shores unlighted, it was out of the question to attempt the navigation of the waters of the Grand Lake during the night. However, it was not until the night of the 11th that Grover was able to complete the embarkation of his division. To understand this it is necessary to observe that Emory and Weitzel, in making the passage of Berwick Bay, were merely crossing a short ferry, so that the boats engaged in the transfer could be loaded rapidly to almost any extent, so long as they remained afloat, and being unloaded with equal facility, were in a few minutes ready to repeat the operation. In Grover's case, however, the infantry, artillery, cavalry, and stores had all to be taken care of at once, with every provision for fighting a battle. For this the artillery was considered indispensable, and it was not without great trouble and long delay that the guns and horses were got afloat. Fate seemed to be against Grover, for after all had been accomplished by the greatest exertion on his part, as well as on the part of his officers and the corps quartermasters, a fog set in so dense that the pilots were unable to see their way. This continued until nine o'clock on the morning of the 12th; then at last the movement began.
About noon, on the 11th of April, Weitzel, leading the advance of the main column, moved forward. At once his skirmishers felt the skirmishers of the enemy, who retired slowly, without attempting any serious opposition. In the evening, Weitzel rested in line of battle a short distance above Pattersonville. Emory followed closely, and went into bivouac on Weitzel's left. The march had not been begun earlier, and the enemy was not pressed, because it was desired to keep him amused until Grover should have gained his rear, and Grover had not yet started.
After the early morning of Sunday, the 12th of April, had been spent in light skirmishing and in demonstrations of the cavalry, designed to observe the enemy, and at the same time to attract and hold his attention, word came that Grover was under way. Banks knew that the passing fleet must soon be in plain sight of the Confederates. Therefore, it was now necessary to move promptly, and to feel the enemy strongly, yet not too strongly, lest he should abandon his position too soon and suddenly spoil all. From this moment it is important to remember that, save in the event of complete success, no word could come from Grover for nearly two days. The first news from him was expected to be the sound of his guns in the enemy's rear.
At eleven o'clock the bugle again sounded the advance. The whole line moved forward, continually skirmishing, until, about four o'clock in the afternoon, the infantry came under fire of the Confederate guns in position on the lines known as Camp Bisland. The line of march led up the right bank of the Atchafalaya until the mouth of the Teche was reached, thence up the Teche, partly astride the stream, yet mainly by the right bank. At first Weitzel formed on the right, Emory on the left, but as the great bend of the Teche was reached, about four miles below Bisland, and by the nature of the ground the front became narrowed at the same time that in following the change of direction of the bayou the line was brought to a wheel, Weitzel took ground to the left in two lines, while Emory advanced Paine's brigade into the front line on Weitzel's right, placed Ingraham in his second line, and made a third line with Godfrey.
Then finding the enemy beyond the Teche too strong for the cavalry to manage single-handed, Banks called on Emory to reinforce the right bank. Emory sent Bryan across with the 175th New York and a section of the 1st Maine battery, commanded by Lieutenant Eben D. Haley. They were to push the enemy back, and to conform to the advance of the main line.
The day was hot, the air close, and the march over the fields of young cane, across or aslant the heavy furrows and into and over the deep ditches, was trying to the men, as yet but little accustomed to marches. Fortunately, however, there was no need of pressing the advance until Grover's guns should be heard. About half-past five in the afternoon a brisk artillery fire began, and was kept up until night fell; then Emory moved the 4th Wisconsin forward to hold a grove in front of a sugar-house, near the bayou, well in advance of his right, in order to prevent the Confederates from occupying it, to the annoyance of the whole line.
After dark all the pickets were thrown well forward in touch with those of the enemy, but the main lines were drawn back out of range, for the sake of a good night's sleep before a hard day's work.
