Taken by the Enemy by Oliver Optic

As the engineer was a cripple, Christy Passford had not expected to have any difficulty in bringing him to terms; and the result justified his calculations. The Leopard was now practically in his possession, for Captain Pecklar was the only person on board, except Percy, who could give him any trouble; and he was too feeble to do any thing.

Percy seemed to be very busy in the pilot-house, going through imaginary evolutions at the wheel, and supposing all sorts of orders, and all kinds of positions in which the tug might be placed. He did not seem even to observe what his companion was doing, though the engineer had been driven into the forecastle in plain sight from the window of the pilot-house.
