No cheese. No exploits. Only surgical precision. This approach costed me less than 10 units.

You are given a Mounted Chief and a large number of 2 key units: Mounted Archers and Mounted Shooters. Your objective is to kill the USA Officers that accompany their infantry blocks. Mounted Officers don't count towards your objective, so you can ignore them.

The USA army will be stationary for a short amount of time. Use this time to snipe the Officers close to the Militiamen with your Mounted Archers, as they have much longer range than them and will kill in a single hit to prevent retaliation. Avoid running into Fusilier range.

Later, the USA will start moving their massive army, starting with their Officers. This will leave them exposed for a short time, away from their meatshields. Use this window of opportunity to bring your Mounted Shooters in, as they excel at hit and run attacks. Pull your Mounted Archers back to provide a clearer view.

The enemy won't attack while they are in transit, so have your Mounted Shooters pick off the Officers one by one. The Officers will move independently of their other units, so they will usually converge in one direction. Wiping them out before they mix into their blob of units will make your life easy and you will have completed the Campaign.

Your British allies in Detroit will stand no chance against the overwhelming enemy numbers (since you will be outnumbered 3 to 1), so trying to defend the city itself is not a reliable strategy. The biggest help they can offer is the Grapeshot from their Cannons, if they manage to shoot before being killed. You can try harassing the enemy from the rear, which can even lure their Officers to you, but it's still a risky approach. On the other hand, USA Cannons are not a threat and will remain completely inactive, unless you damage them first.
