When Rentap realised that he could not continue defending the fortress, he commanded his warriors to leave it from the opposite side of the mountain. The attackers, under cover of the musket fire, rushed over the neck rock and through the breaches made by their cannon. They discovered that Rentap and his warriors had escaped, leaving only the dead and the dying. They found the arms captured by Rentap when he fought against Lee and Brereton at Lintang Batang in 1853, a large quantity of gunpowder, and the "One-armed Bachelor".
