Meanwhile on the left of the Teche the main body moved forward in two lines of battalions deployed, Paine on the right and Weitzel on the left, while Ingraham, in column of companies, formed the reserve for both. Paine's first line on the right, nearest the bayou, was composed of the 4th Wisconsin and 8th New Hampshire, his second line of the 133d New York and the 173d New York. Mack's 20-pounders commanded the bayou road, and Duryea went into battery in advance of the centre, between Paine and Weitzel. Weitzel's front line was composed of the 8th Vermont and 114th New York, with the 12th Connecticut, 160th New York, and 75th New York in the second line. The guns of Bainbridge and Carruth went into battery near the left flank, and working slowly kept down the fire of the Confederate artillery in their front. When the fire of musketry became hot, Weitzel sent the 75th New York to try to gain the canebrake on the left, in advance of the enemy's works, with a view of turning that flank. Of this movement Taylor says in his report that it was twice repulsed by the 5th Texas and Waller's battalion, under Green, and the 28th Louisiana, Colonel Gray, aided by the guns of Semmes's battery and the Valverde battery. However, the counter-movement on the part of the Confederates, being begun in plain view, was instantly seen, and Banks sent word to Weitzel to check it. With this object, Weitzel ordered the 114th New York to go to the support of the 75th. A brisk fight followed, without material advantage to either side. In truth, the canebrake formed an impenetrable obstacle to the combatants, who, when once they had passed within the outer edge of the tangle, were unable either to see or approach one another, although the struggle was plainly visible from the front of both armies. The reserve of Parrott guns, manned by the 1st Indiana and composed of four 30-pounders and four 20-pounders, was posted under McMillan to cover the left flank and the broken centre where it was pierced by the bayou, as well as to watch for the return of the _Diana_ to activity. Toward evening the remaining guns of the 1st Indiana, two 12-pounder rifles under Cox, after being posted in support of the centre, were sent to the left to assist Bainbridge and Carruth, whose ammunition was giving out.
