OPERATIONS ON THE TECHE AND ATCHAFALAYA RIVERS, LA.
April 13–20, 1863.
General Banks having concentrated his forces at Brashear, General Weitzel’s brigade was crossed over to Berwick on the 10th of April, without opposition, followed on the succeeding day by General Emory’s division, and both commands advanced upon the fortified position a few miles above Pattersonville. On the 13th, there was considerable artillery firing, in which the gunboat Diana, a late Federal capture, took active part. On the 12th, the division of General Grover left Brashear on the gunboats Clifton, Estrella, Arizona, and Calhoun, and transports, and proceeded up the Atchafalaya river, which joins the Teche at Berwick City, into Lake Chetimacha. The object was to get into the rear of the enemy, and if possible cut off his retreat if he evacuated his position, or to assail him in rear at the time of the attack in front. The expedition effected a landing early the next morning, about three miles west of Franklin, near a spot called Irish Bend. At this time, the gunboat Queen of the West, which had been captured previously by the enemy, was blown up and destroyed on the lake. Skirmishing immediately ensued with a small force of the enemy, that fell back as General Grover advanced. His position was about eleven miles distant from General Banks.
