After two days of pursuit, the Confederate rams CSS Webb and CSS Queen of the West hauled into sight of the slow-moving USS Indianola. The Union ship decided to fight, and lashed the coal barges she had been towing to either side to protect against ramming. But the Federals had made a key mistake: the sun had set, and Indianola's gunports did not let in enough moonlight for her cannoneers to see their targets. There was, however, enough light to ram by.
The Northern shots missed the Rebel rams as they closed, and then they came in from the sides where Indianola had no guns. The ironclad was rammed again and again, tearing away the coal barges. Rifle fire from the Confederates made things even more difficult for the Union ship, but captain Brown went out on deck since he couldn't see enough from the pilot-house. The bullets managed to miss him -- it was not a night for accurate shooting on either side -- but he was nearly thrown overboard by the shock of the next ramming. Brown decided it was time to retreat.
It was a fatal mistake. Even without the coal barges, Indianola had no chance of outrunning the Confederate rams. The Webb delivered one mighty blow to the stern, tearing deep into the ironclad's hull and rendering her nearly unmanueverable and sinking. With another Southern steamer loaded with boarding troops approaching, Captain Brown called out his surrender.
The firing and ramming stopped, but the Indianola was still flooding. She could not turn by herself since her rudders were disabled. The Confederates tried to tow her to the river's bank, but instead managed something half-way between sinking and running aground, with the ship settling in ten feet (3 m) of water. It would be a much more difficult job for the Southerners to raise and repair her than for the Queen of the West -- but not impossible.
In Washington, President Lincoln signed the law creating the Territory of Arizona, organized from the Territory of New Mexico and a bit of present-day Nevada. This was ironic, because the Confederacy had claimed a "Territory of Arizona" for itself, while the North had insisted that the Territory of New Mexico comprised both areas and would not be divided. However, the Confederate idea had been to divide along a line running East-West. The Union government had now countered by using a dividing line running North-South, and placed the capital of the new territory in Prescott, where Unionist sympathies were stronger.
