In 222, Wu Can participated in the Battle of Dongkou against Eastern Wu's rival state, Cao Wei. He accompanied the Wu generals Lü Fan, He Qi and others to resist the Wei forces led by Cao Xiu. There was stormy weather at the time so the Wu ships became separated from each other when the connecting ropes broke. Some of the ships drifted towards the Wei base and ended up being captured by the enemy while others capsized and threw their sailors overboard. Wu Can and another officer, Huang Yuan (黃淵), were on one of the larger ships which managed to prevail in the storm. The sailors on the ship refused to allow the survivors in the water on board because they feared that their ship would sink due to overloading, so they brandished their weapons at the survivors who were attempting to climb on board. However, Wu Can and Huang Yuan gave orders to their men to save as many survivors as possible. When the men were reluctant to follow orders due to fear of overloading, Wu Can said, "If the ship sinks, we'll all die together! We shouldn't abandon those who are in need of help." Through their efforts, Wu Can and Huang Yuan succeeded in rescuing more than 100 survivors.
