American Military History, Volume 1 by Richard W. Stewart

The United States as a nation was in its origins a product of English expansion in the New World in the seventeenth and eighteenth centuries, a part of the general outward thrust of West European peoples in this epoch. British people and institutions, transplanted to a new continent and mixed with people of different origins, underwent changes that eventually produced a distinctive American culture. In no area was the interaction of the two influences-European heredity and American environment-more apparent than in the shaping of the military institutions of the new nation.
