Godsacre

Godsacre was a Colonel in 1881. He found Friday (Ice Warrior) and revived him. He helped repair Friday's ship, enabling them to reach Mars. Godsacre was secretly a deserter who had been hanged for cowardice, but survived. Captain Catchlove was aware of this and used it to blackmail Godsacre. When they reached Mars Friday woke his Empress Iraxxa. Catchlove revealed Godsacre's secret, arresting him, the Doctor and Bill. They were freed by Friday and when Catchlove tried to escape by holding the Martian Empress hostage Godsacre shot his treacherous Captain dead. He agreed to serve Iraxxa and left with the Martians.
