April 11, 1863, The New York Herald
The report from Charleston is that the Keokuk was disabled on Tuesday, and on the following day was sunk on the beach off Morris Island.
Subjoined is a sketch of her: – […..]
The Keokuk was designed by Mr. C. W. Whitney, of this city, and was built at the yard of J. S. Underhill & Co., Dry Dock Iron Works. She was launched in the early part of last winter, and sailed from New York on the 11th of March, arriving at Port Royal on the 26th. The following is a description of the vessel: –
The Keokuk was not only a two turreted vessel, but was also a ram. She was smaller than the Ericsson Monitors, being one hundred and fifty-nine feet six inches over all, including the ram, which was five feet long. She had a beam of thirty-six feet, with a depth of hold of thirteen feet six inches, and drew nine feet of water. Her sides sloped inward at an angle of thirty-seven degrees, to shed the enemy’s shot.
She was built of iron, and her armor extended nearly four feet below the water line. The horizontal deck was five feet above the water line. Her propulsive power was furnished by two propellers and two engines of five hundred horse power. The hull of the vessel was constructed of half-inch rolled iron. She had three keelsons running the whole length of the vessel, and two fore and aft bulkheads, leaving on each side a space and forming an inner skin, which would probably keep out the water in the event of the outer skin being pierced by shot. In addition to these she had two bulkheads – one forward and one aft – which could be filled with water, so as to settle the vessel down while in action. These could be filled in fifteen minutes and pumped out in forty minutes. In using the ram, should the vessel be wrenched so as to cause leakage, the compartment alluded to was to preserve the vessel from sinking. The vessel was submerged one foot by the appliance of these water tanks. [continue reading…]
