Taylor, when he first learned that the gunboats and transports had passed up Grand Lake, had sent Vincent, with the 2d Louisiana cavalry and a section of Cornay's battery, to Verdun landing, about four miles behind Camp Bisland, to observe and oppose the movement. This was about noon on Sunday, the 12th. In the evening, hearing of the progress of the fleet, Taylor sent a second section of Cornay's battery to the lake, and going himself to Vincent ordered him to follow the movement and try to prevent a landing. The next morning Taylor sent Reily with the 4th Texas, to join Vincent and aid him in retarding Grover's progress.
Taylor seems to have censured Vincent for letting Grover land, yet in truth Vincent was not to blame. The line he had to watch was too long for his numbers, and the Union flotilla could and did move more rapidly on the lake than the Confederate troops by the roads. When he had stationed his pickets at the probable landing-places, and taken up a central position to support them, he had done all that lay in his power. The range and weight of the 9-inch shells of the navy were alone enough to put a serious opposition to the landing out of the question, but as soon as Vincent found where the attempt was to be made, he disposed his men and guns to retard it. Two of Cornay's guns even tried, ineffectually of course, to destroy the transports: Cooke quickly drove them off.
As Holcomb's skirmishers deployed they were met by a brisk fusillade from Vincent's men strongly posted in ambush behind a high fence in the thick wood that skirts the shore; but when Holcomb advanced his battalion Vincent's men fell back on their main body and left the wood to Holcomb, who immediately moved to the edge of the clearing and held it, observing the enemy on the farther border. This was Vincent with his regiment and the four guns of Corney; and from this moment all that was happening on the lake shore passed unseen by the Confederates.
Meanwhile the landing went on very slowly, for the transports could not come nearer to the beach than a hundred yards, and, although the foot-soldiers were able to jump overboard and scramble ashore, and the horses could also take to the water, it was necessary to make a bridge of flats for the guns and caissons of the artillery. Thus it was four o'clock in the afternoon before the whole division found itself assembled on the plantation of Duncan McWilliams on the shore of the lake, with the Teche at the upper reach of Irish Bend four miles to the southward, and Charenton in the hollow of Indian Bend lying but two miles toward the southwest. There were roads in either direction, but Irish Bend was the way to Franklin, and to Franklin Grover was under orders to go.
