潘璋
In 227, Pan Zhang followed Sun Quan to a battle against Wei forces at Shiyang County (石陽縣; in present-day Hanchuan, Hubei). He was tasked with covering the rear as Sun Quan's men were withdrawing after the battle. However, he lowered his guard that night and could not hold up against the enemy when they attacked. Zhu Ran led reinforcements to resist the enemy's advance until Sun Quan's forces at the front had completely retreated before he withdrew.
