Dmitri Zheng

Dmitri Zheng was a Commander in the UNSC Navy. In 2534, he had command of a UNSC Light Frigate, Midsummer Night. Commander Zheng had lost his previous frigate by ramming a Covenant destroyer. Many people thought that he had done this in anger and revenge, but Zheng later told Lt. Jacob Keyes that he had run out of tactical options. Zheng only avoided a court martial because the destroyer was subsequently taken out by another ship's MAC.

Death
Zheng was shot by Lieutenant Campbell, an Insurrectionist sympathizer. After being shot, Zheng realized that the ship was going to be under siege so instead of receiving medical attention he went to lock the codes to the Shiva Nuclear Mines. After completing his mission he transmitted the ship's surrender to the Rubble defense. He died after talking to Keyes about the truth behind his reasoning to ramming the ship under his command into a Covenant Destroyer; it was not because of revenge, but because it was the last resort he had. He died from loss of blood and passed the Commanding Officer status to Keyes.
