These difficulties were enhanced by obstructions placed in the streams, and fortifications at important points.
Near
Pattersonville, on the
Teche, was an earthwork called
Fort Bisland, with revetments; and well up the
Atchafalaya, at
Butte à la Rose, was another.
There was also an armed steamer called the
J. A. Cotton on the
Bayou Teche.
These were intended to dispute the passage of those important waters by National gun-boats from
Red River, or forces by land from New Orleans.
Some operations by National forces had already been made on the
Teche, and it was now determined to drive the
Confederates from their strong places in the vicinity of
Brashear City, and to destroy their gun-boat.
An expedition for that purpose was led by
General Weitzel, accompanied by a squadron of gunboats under
Commodore McKean Buchanan, who fought his traitor brother so bravely on the
Congress in

Hampton Roads.
1 Weitzel left
Thibodeaux on the 11th of January,
and placing his infantry on the gun-boats at
Brashear City, he sent his cavalry and artillery by land.
2 All moved slowly up the
Bayou to
Pattersonville, and at Carney's Bridge, just above, they encountered the first formidable obstacles.
These consisted of the piles of the demolished bridge, against which lay a sunken old steamboat laden with brick, and in the bayou below, some torpedoes.
Just above these was the very formidable steamer
Cotton, ready for battle, and batteries (one of them
Fort Bisland) were planted on each side of the bayou, and defended by the Twenty-eighth Louisiana and artillerymen, in all about eleven hundred men.
Buchanan proceeded to attack the obstructions and the batteries on the morning of the 15th,
when, after a short engagement, the stern of the
Kinsman was lifted fearfully but not fatally by a torpedo that exploded under it. Just then a negro, who had escaped from the
Cotton for the purpose, warned them of another torpedo just ahead.
