While you get an afwul lot of Osprey artwork for your buck, this compendium falls short as an overview of the Seven Years' War in North America - which ended 3 years prior to the global conflict. The abbreviated Men-at-Arms and Campaign titles intersect each other.
So, after the first clashes in the Ohio wilderness and the massacre at Fort william Henry, we pause to look at the tactics of French and British regulars, as opposed to the "forest guerilla" art of war practiced by the Native Americans and Canadian frontiersmen. Given that the latter were schooled on the plains of Europe and the former between the Acadian pines, it was clear who could learn a thing or two from who. Fort Duquesne already played out like a lake Trasimene in the woods; both standing armies responded by developping Light Infantry and, fiercely independent from your average redcoat, the famous Rangers.
The turn of the tide in 1758-59, however, was made with good ol' fashioned European methods: the siege of Louisburg's Vauban forts unlocked the gate to New France and similar rustic trenches made the Great Lakes untenable. Wolfe's famous scaling of the Quebec cliffs virtually decimated the capital's garrison with a single disciplined volley. The valiant storming of the abbatis at Ticonderoga by the Black Watch was hardly a novelty, either.
France had a miniscule manpower base to cover an enermous territory that no amount of metropolitan reinforcements could alleviate; Britain, by contrast, had superior numbers and a less interdicted transatlantic supply line... advantages that would be reversed during the American Revolution.
