December view of the Potomac with Fort Washington near photo's center. Piscataway Creek is just to the right of center. The Potomac takes a turn to the left at Fort Washington to run almost due north.
The fort was sited at this point to take advantage of that turn. Ships sailing upriver would be unable to bring broadside guns to bear and the fort's guns could rake the ship's bow on. This was vulnerable position for ships putting masts at increased risk and allowing any hull hits to do more damage as the ball crashed down the long axis.
