Final answer:
The British continental style of fighting became more effective over time due to increased military presence and alliances with Native Americans, leading to territorial gains. However, the resulting British policies post-war, aimed at increasing revenue, sowed seeds for colonial unrest and eventual rebellion.
Step-by-step explanation:
The effectiveness of the British continental style of fighting evolved significantly throughout the period preceding and following the French and Indian War. Initially, this strategy was less successful due to small-scale operations and the lack of decisive victories. However, with the increase in troops and Native American allies, the British forces shifted the balance of power in their favor.
The adoption of these new tactics contributed to the conquest of crucial territories like Fort Louisburg. After the war, Britain's Imperial policies and the expenses of maintaining new territories led to tensions and the colonial cry of "no taxation without representation" which laid the groundwork for the American Revolutionary War. Post-war, the Treaty of Paris in 1763 granted Britain vast new territories but also ushered in challenges with the Native American tribes, most notably in Pontiac's Rebellion.
This along with the shift in policy from salutary neglect to more stringent taxation and control, highlighted the differences between colonial and British interests. Overall, the British military methods evolved from ineffective to effective during their engagements with the French, ultimately resulting in a temporary imperial expansion at significant financial and political cost.
