The Seven Years War began unofficially in 1754 in the Ohio Valley and was later transferred to Europe. This reversed the usual situation; most wars started in Europe and were transferred to North America. The problem was both French and British settlements were expanding. It was a matter of time before the two sides would clash over the same territory. In 1749 a group of British buisness people secured a grant of 200,000 hecters of the Ohio Valley for settlement even though the land was claimed by the French. The French built a chain of forts to secure their land claim and attacked British settlers.
In 1755 the British government sent soldiers to defeate the French and their native allies and conqueor all the French fur trading forts in America and Canada. British General Wolfe successfully landed 4,500 men in Quebec to the suprise of the French. Many of the French soldiers were not in Quebec as they were tending to their farms. General Wolfe ordered his men in the cover of night to scale the high cliffs of Quebec and attack the City on the Plains of Abraham and by sunrise they were ready to attack!
French General Montclam acted hasitly, rather than waiting for reinforcements, he decided to engage the British. The French had a force of close to 4,000 men made up of farmers, volunteers and natives vs. the British professional soldiers. The disciplined British soldiers fired volley after volley on the raggedly French soldiers. The Battle was over in half an hour as the British handly defeated the French. During the Battle both General Montcalm and General Wolfe were killed.
