Guerilla (Day of the Daleks)

An unnamed guerilla fought against the Daleks in an alternative 22nd century.

Biography
Using stolen Dalek plans, a time machine had been built so the guerilla could travel back in time to Auderly House in the 1970s and kill Sir Reginald Styles, the person assumed to have started escalations into World War III.

One night, the guerrilla tried to kill Sir Reginald but failed. The next day, when he tried to return to his own time, he was attacked and left for dead by two Ogrons who had followed him.

After UNIT troops found his body, Captain Yates had Sergeant Benton escort him to a hospital. While in the ambulance, the Third Doctor meddled with his time machine, which appeared to transport the guerrilla back to his home era.

Later, when Jo Grant threatened to destroy the guerilla's time machine and trap Anat, Boaz and Shura in the 20th century forever, Anat claimed the man who used the machine was dead, and his body was back in their time zone. (TV: Day of the Daleks)
