Answer:
The answer to the question: What turning point of the war occurred in 1757 for the English, would be: The Battle of the Plains of Abraham, better known as the Siege of Quebec.
Step-by-step explanation:
During the French and Indian War, which was the American front of the Seven Years War which was being fought in Europe, between 1754 and 1763, the British almost saw total defeat on their American lands when the French at the Quebec territory, under the control of General Louis-Joseph de Montcalm, was successful in detaining the attack from British commander James Wolfe attempted to take over the city of Quebec. However, Wolfe, realizing in 1757 that it was impossible to do, and that the only way to win was through open battle, draws the French away from the fortified city of Quebec, and confront them on the Plains of Abraham. The British win, and thus gain control over the Quebec Province. At this point, the French and Indian War takes a turn in favor of the British.
