Answer:
Something unique about the war was that we generally did not take, occupy, and control land, our strategy was to kill the enemy
The correct answer is Fort Duquesne. At first the French controlled it and the British attacked to take it from them. The french withdrew and destroyed the fort when they realized the British were going to win and this became a major victory for the British army.
Judging from your other questions, I would guess the Aztecs, because they had an extremely advanced civilization relative to their time period. However, you might want a second opinion to verify this. Hope this helps.
