The French and the British are at each other’s throats once again and this time you are tasked with booting the French off the North American mainland. They have a spine of forts which they have constructed and you’ll need to march north and claim them for yourself. The first target is Algonquin territory but access to Fort Niagara is blocked by another fort. The advisor suggests brokering an alliance with the Iroquois and cutting through their land round the fort to reach your target. To be honest Fort Duquesne is not hard to take. Combine your armies and march straight for it. Build the farm and the shipyard in Virginia and make an alliance and trade agreement with the Iroquois. (Getting the alliance and going through Iroquois territory to take Duquesne works, but it takes a couple extra turns getting your army through the forest).
Once you have Fort Duquesne, assuming you took it with minimal losses, press straight on and grab Fort Niagara. If you need to you can replenish your force here retraining as necessary. Once you have taken the settlement you’ll need to build some ships and take Louisbourg. With the shipyard built start on a dockyard and build a couple of extra units in Virginia.
