What this topic is asking
Topic 3.5 asks you to explain the course and outcome of the War of Independence (1775 to 1783) and, crucially, why the colonists won. The exam does not want a battle-by-battle narrative; it wants the decisive turning points, the role of foreign aid, and the reasons a much weaker side defeated the world's leading military power.
The course of the war
Carry a short spine of events into the exam.
- 1775: fighting begins at Lexington and Concord; Washington takes command of the Continental Army.
- 1776: Common Sense and the Declaration of Independence; the colonies commit to full separation.
- 1777: the American victory at Saratoga, the war's strategic turning point.
- 1778: the French alliance, bringing foreign troops, money, and a navy.
- 1781: the British surrender at Yorktown after a combined Franco-American siege.
- 1783: the Treaty of Paris recognizes American independence.
The turning point and the French alliance
Why the colonists won
The Americans were outmatched in men, money, and navy, so the exam rewards explaining their compensating advantages:
- A defensive war on home ground. Britain had to project power across an ocean and occupy a vast, hostile territory.
- Foreign aid. French (and later Spanish and Dutch) assistance supplied what the colonists lacked, especially naval power.
- Leadership and persistence. Washington kept the army intact and chose to outlast rather than out-fight the British.
- Motivation. Colonists fought for their homes and a cause; many were willing to endure where a distant Britain's will eventually flagged.
The outcome
The Treaty of Paris of 1783 did three things the exam may reward: it recognized American independence, set the western boundary at the Mississippi River, and granted fishing rights off Canada. The new nation now faced the harder task of governing itself.
