As an extra precaution, Cruger's soldiers built an elongated mound inside the Star Fort known as a traverse. It was a defensive position in the event that the attackers breached the fort walls. In addition, the traverse provided protection from the marksmen atop the rifle tower.
A tactic of siege warfare was to cut the enemy from supplies and necessities. The Loyalists had limited access to water due to Greene's riflemen guarding the Spring Branch. As a result, the loyalists attempted to find water by digging a well inside the Star Fort. After digging 25 feet and finding nothing but more dirt, slaves carried in buckets of water underneath the night sky using the communication trench.
