What were the two major challenges that Major Montcalm had to face just before The Battle of the Plains of Abraham began:

british and france

Explanation:

One, the British under General James Wolfe achieved a dramatic victory when they scaled the cliffs over the City of Quebec to defeat French forces. Second, France was preoccupied by hostilities from other colonies that hoped to destroy them as a commercial rival.

Well, I am only aware of one challenge; Montcalms men were 16 kilometers away at the Beauport Short meaning that he didnt have his trained troops to train alongside him in the battle.
