A naval expedition to the mouth of the Sabine river, in Texas, was undertaken by General Banks, who dispatched General Franklin with four thousand men in four army transports, to capture the forts at Sabine Pass, at the mouth of the river, which forms the boundary line between Texas and Louisiana. The armed steamers employed were the Clifton, Sachem, Arizona, and Granite City, and the naval forces were commanded by Lieutenant Crocker. Early on the morning of September 8th, the Clifton stood in the bay and opened on the fort, to which no reply was made. At 9 A. M. the Sachem, Arizona, and Granite City, followed by the transports, stood over the bar, and, with much difficulty, owing to the low water, reached an anchorage about two miles from the fort at 11 A. M. About the middle of the afternoon the Sachem, followed by the Arizona, advanced up the eastern channel to draw the fire of the forts, while the Clifton advanced up the western channel. The Granite City remained to cover the landing of a division of troops under General Weitzel. No reply was made to the fire of the gunboats until they were abreast of the forts, when eight guns opened fire upon them. Three of these were rifled. Almost at the same moment the Clifton and Sachem were struck in their boilers and both vessels enveloped in steam. The Arizona, not having room to pass the Sachem, then backed down the channel until she grounded by the stern, when the ebb-tide caught her bows and swung her across the channel. White flags were raised on the Clifton and Sachem, and within twenty minutes they were taken in tow by the enemy. The naval force of the expedition being thus disabled, the transports moved out of the bay. The Arizona was got afloat during the night, and followed. The expedition then returned to Brashear City. The officers and crews of the Clifton and Sachem, and about ninety sharpshooters who were on board were captured, and the loss in killed and wounded was about thirty. After remaining at Brashear City some time, the military force moved to Franklin and Vermillionville. On the 27th of October an expedition under General Banks put to sea from New Orleans. It consisted of about twenty vessels, accompanied by the gunboats Owasco, Virginia, and Monongahela, which sailed to the mouth of the Rio Grande river, the boundary between Texas and Mexico. Brownsville was occupied by Federal troops, which did much to check the designs of the French Emperor. An American army was now placed on the frontier, prepared to check any open demonstration of sympathy between the armies of Davis and Napoleon. Western Louisiana was again the scene of military operations in the Teche district, where General Washburn’s command was attacked on the 5th of November, and after a severe struggle, he succeeded in beating off the enemy with a loss of one hundred killed and two hundred prisoners. The Federal loss was forty killed. NAVAL OPERATIONS IN 1863.
