Sachem was captured at Sabine Pass. From Wiki:
Second Battle of Sabine Pass[edit]
Sachem (right) is captured along with
USS Clifton
Early in September,
Sachem was assigned to a joint Army-Navy expeditionary force mounted at New Orleans to
attack Sabine Pass, Texas. Possession of this port would close another important Confederate blockade running center and provide the Union with a base for a thrust into the interior of Texas.
Sachem arrived off Sabine Pass on the evening of the 7th, followed
USS Clifton across the bar and entered the harbor there the next day. That afternoon,
Sachem, followed by
USS Arizona, advanced up the Louisiana Channel while
Clifton and
USS Granite City moved forward along the Texas shore.
Sachem and
Clifton opened fire on the Confederate battery at Fort Griffin, but the Confederate guns remained silent until the Union gunboats were at close range. Then they countered with a devastating cannonade. A shot through her boiler totally disabled
Sachem and another cut
Clifton’s wheel rope causing her to run aground under the Southern guns. Nevertheless, the damaged gunboats continued their struggle until heavy casualties forced
Clifton to surrender.
Arizona and
Granite City then began to withdraw; so Lt. Johnson, with no possibility of saving his ship, ordered her Parrott gun spiked; her magazine flooded; and her signal book and spy glass destroyed. He then had her flag hauled down and a white flag hoisted.
Confederate
cotton-clad steamer
CSS Uncle Ben then pulled up to
Sachem and towed the gunboat to Sabine City. On 17 October,
Sachem sailed for
Orange, Texas, and operated under the
Texas Marine Department supporting the Confederate Army. In March 1864,
Sachem was back at Sabine Pass; and, in April, was said to be commanded by a noted blockade runner of Galveston, John Davisson; was reportedly laden with cotton and awaiting a chance to slip through the blockade. However, no further record of her career has been found.

I'll have to look up when
Granite City may have been taken. House must have been acting either as a prize agent for the captured vessel(s) or the purchaser?
