“This is crazy.”

“So is war, Commander,” Brown said over his shoulder as he spurred his horse and rode off, followed by his small detachment disguised as Union cavalry.

There was no more time, no more interruptions to delay the Texas’ voyage to hell. Tombs turned to Craven.

“Lieutenant, escort our passenger to my quarters and tell Chief Engineer O’Hare to send a mechanic to remove the manacles. I won’t die as commander of a slave ship.”

The bearded man smiled at Tombs. “Thank you, Commander. I’m grateful for your kindness.”

“Do not thank me,” said Tombs grimly. “By sun up we’ll all be introducing ourselves to the devil.”

Ever so gradually at first, then faster and faster, the Texas began to steam downriver, helped along by the 2-knot current. No wind stirred, and except for the throb of the engines, the river ran silent. In the pale light of a quarter moon, she slid across the black water like a wraith, more sensed than seen, almost an illusion.

She seemed to have no substance, no solidity. Only her movement gave her away, revealing a spectral outline gliding past a motionless shore. Designed specifically for one mission, one voyage, tier builders had constructed a marvelous machine, the finest fighting machine the Confederates had put afloat during the four years of war.

She was a twin-screw, twin-engined vessel, 190 feet in length, 40 feet of beam, and drawing only 11 feet of water. The sloping 12-foot-high sides of her casemate were angled inward at 30 degrees and covered with 6 inches of iron plate backed by 12 inches of cotton compressed by 20 inches of oak and pine. Her armor continued under the waterline, forming a curled knuckle that extended out from the hull.

The Texas carried only four guns, but they had a vicious bite. Two 100-pound Blakely rifled guns were mounted fore and aft on pivots that allowed them to be fired in broadside while two 9-inch, 64pounders covered the port and starboard.

Unlike other ironclads whose machinery had been stripped out of commercial steamers, her engines were big, powerful, and brand new. Her heavy boilers lay below the waterline, and the 9-foot screws could push her hull through calm water at 14 knots, the nautical equivalent of 16 mph-tremendous speed unmatched by any armored ship in both navies.

Tombs was proud of his ship, yet saddened too, knowing that her life might well be short. But he was determined that the two of them would write a fitting epitaph to the closing glory of the Confederate states.

He climbed a ladder from the gun deck and entered the pilothouse, a small structure on the forward section of the casemate that was shaped like a pyramid with the top leveled off. He stared through the eye slits at the darkness and then nodded toward the strangely silent Chief Pilot, Leigh Hunt.

“We’ll be under full steam the entire trip to the sea, Mr. Hunt. You’ll have to bear a sharp eye to keep us from running aground.”
