The Royal Welch Fusiliers Redoubt is a large, star shaped earthen fort high above the York River. The redoubt was made by digging a deep trench and creating a mound with spiked poles. It prevented attacks on the troops hidden behind the embankments and had only one small entryway. From this location cannon fire could be directed at passing boats.
The Royal Welch Fusiliers successfully repelled French efforts to take the position until the British surrendered.
