Wargames provide unbelievable opportunities for learning. They pique the interest and passion of the casual tactician or historian and assist the professional military officer in operational planning and execution. Their capacity for imparting knowledge can either supplant or complement lectures. Wargames are a valuable tool for the molding of the professional military officer.During the interwar period the United States Naval War College (NWC) used wargames extensively as a method of teaching both history and current tactics to aspiring naval officers. The NWC believed in wargaming's value so much, an entire building was dedicated to conducting the curriculum's games. On the game floor wars against Great Britain and Japan were repeatedly fought, and the evolution of multiple war plans stemmed from the spirited debates and uncanny tactics the games generated. An entire generation of naval officer brought what they had learned from the NWC's wargames to the fleet.Wargames directly benefited the U.S. Navy's interwar Fleet Exercises. The exercises were the pinnacle of the fleet's annual training. The lessons learned in Newport were tested in conditions resembling war. Feedback from the exercises both validated and reputed Newport's theories and the war plans' requirements (which the exercises were built to test).World War II was the ultimate test of Newport's lessons. Battles at Savo Island in the Solomon Islands, Peleliu, and Samar in the Philippines pointed out strengths and weaknesses in the NWC's strategic and tactical curricula. Looking into how wargames (simulations) affected war (reality) can provide a model for future training opportunities, particularly in fiscally challenging times; the rising cost of fuel and maintenance of ships underway inspires alternative methods of education and preparation for war.
