American Revolution: Capture of Armourer's Fort

(This is a fictional location and a fictional battle in a very real war) After we have handed crushing defeats to the rebel scum, they have captured two forts. One of them is a small wooden outpost controlling a junction of a small road. We will capture it to provide a staging point to attack Armourer's Fort, an intimidating and well-defended structure. If we succeed, the rebels will be severely beaten and we might be able to crush the rest of them.
