Steam power brought a major change. Although it proved an excellent method of moving large numbers of troops quickly over long distances, as was shown in the American Civil War and World War I, steam power did not prove to be viable on the battlefields itself. The development of the internal combustion engine kick-started the mechanization of warfare. On October 19, 1914, British troops moved to the from in London omnibuses requisitioned by the army and during World War I trucks would begin to be used in every army. Tracked vehicles entered combat during the Somme offensive of 1916, and this was the precursor to the more extensive use of armored fighting vehicles in World War II, the Cold War, and the wars in the Middle East. Mechanized Warfare tells this story from the first armored cars and lozenge-shaped tanks of World War I, through the developmental 1920s and 1930s, to Blitzkrieg and World War II, when mechanized warfare came of age, even though German successes were backed up by long lines of footsloggers and horses. Today, the tank is still queen of the battlefield.
