Lastly, the political context was crucial. Had all the colonies in the
Western Hemisphere rebelled, then the British would n ot hav e stood a
chance, but the economically most crucial o nes (the We st Indian sugar
islands, such as Jamaica a nd Barbados), and the strategical ly vital ones,
those with the naval b ases (Nova Scotia, Jamaica, and Antigua), did not
rebel. As a result, the British had safe bases—to the north a nd the so uth
of the Thirteen Colonies, from which to mount op erations. When, in
March 1 776, General Sir William Howe withdrew from Boston, leaving
the Patriots, whose artillery now dominated the harbor, victoriously in
control of the Thirteen Colonies, he did not have to retreat to Britain.
Instead, he sailed to Halifax and rebuilt his force, so that, that summer,
the Empire could strike back, Howe landing on Staten Island at the start
of the New York campaign. The eventually successful British defense of
Canada against American attack in 1775–1776 ensured that, as with East
Florida (modern Florida minus the Panhandle), there were also land fron-
tiers across which the Patriots could be attacked. Burgoyne mishandled
the invasion south from Canada in 1777, but the strategic challenge posed
by British forces there would have been more apparent had Carleton in
1776 and Burgoyne in 1777 been more successful.
More serious from the American perspective were the Loyalists, for this
was a civil conflict, the first major American civil war. Loyalists fought
and died for their vision of America, just a s Patriots did, and in some
areas, especially Georgia, North Carolina, the eastern shore of the Chesa-
peake, and parts of New Jersey and New York, Loyalists were numerous.
Furthermore, the boundaries between Patriots and noncommitted, and
between noncommitted and Loyalists were porous, not fixed. Politically,
the British had to move as many Americans as possible across these boun-
daries; and American strategy provided them with their opportunity. The
American emphasis on positi on warfare in order to protect their major
cities (New York in 1776, Philadelphia in 1777, and Charleston in 1780),
or to capture those in British hands (B oston in 1775, Philadelphia in
1777, Newport in 1778, and Savannah in 1779), gave the British opportuni-
ties to defeat their opponents and thus to affect opinion within America.
In doing so, they were helped by the problems facing the Americans. To
create and sustain an effective army was no easy task, and the Americans
encountered many difficulties in doing both. Money and supplies were
seriou s issues, and much of Washington’s correspondence is an account
of organization and improvisation under pressure. The antiauthoritarian
character of the American Revolution, and the absence of national institu-
tions, made it difficult to create a viable national military system for land
—and, even more, sea—power. Initial enlistments for one year did not
amount to a standing army. In early 1777, for example, Washington’s
army was badly aff ected by desertion, expiring enlistme nts, and supply
problems. There were difficult negotiations over the militia, as seen in
