2010, p. 46 Because Monitor was an experimental craft, urgently needed, hurriedly constructed and almost immediately put to sea, a number of problems were discovered during her maiden voyage to Hampton Roads and during the battle there. Yet Monitor was still able to challenge Virginia and prevent her from further destroying the remaining ships in the Union flotilla blockading Hampton Roads. During the "boom time" of the Civil War, Ericsson could have made a fortune with his inventions used in Monitor, but instead gave the U.S. government all his Monitor patent rights saying it was his "contribution to the glorious Union cause". CrewMonitors crew were all volunteers and totaled 49 officers and enlisted men. The ship required ten officers: a commander, an executive officer, four engineers, one medical officer, two masters and a paymaster. Before Worden was allowed to select, assemble, and commit a crew to Monitor, the vessel had to be completed. The original officers at the time of Monitors commissioning were: Four of the officers were Line officers and responsible for the handling of the vessel and operation of guns during battle, while the engineering officers were considered a class unto themselves. In Monitors turret, Greene and Stodder supervised loading and firing of the two 11-inch Dahlgrens. Each gun was crewed by eight men. In Worden's report of 27 January 1862 to Welles, he stated he believed 17 men and 2 officers would be the maximum number in the turret that allowed the crew to work without getting in each other's way.Monitor also required petty officers: among them was Daniel Toffey, Worden's nephew. Worden had selected Toffey to serve as his captain's clerk. Two black Americans were also among the enlisted men in the crew. Living quarters for the senior officers consisted of eight separate well-furnished cabins, each provided with a small oak table and chair, an oil lamp, shelves and drawers and a canvas floor covering covered with a rug. The entire crew were given goat-skin mats to sleep on. Lighting for each living area was provided by small skylights in the deck above, which were covered by an iron hatch during battle. The officer's wardroom was located forward of the berth deck where officers would eat their meals, hold meetings or socialize during what little spare time they had. It was well furnished with an oriental rug, a large oak table and other such items. Ericsson
