Washington recognized that Bound Brook itself was a difficult place to defend. On May 26 he withdrew the garrison, and on May 28, he moved part of his army from Morristown to a new entrenched camp near Middle Brook, just north of Bound Brook but well protected between the first and second Watchung Mountain ranges; other troops were stationed near Princeton. From the top of the Watchung Mountains, Washington monitored British movements while the two sides continued to skirmish. Both sides also engaged in intelligence gathering, each trying to determine the strength and intentions of the other.
