General Carrington was a British military officer and the head of the Space Security Department.

He had been an astronaut on Mars Probe 6, partnered with Jim Daniels. They landed on Mars and encountered aliens who — not realising that their touch was fatal to humans — accidentally killed Daniels.

Afterwards, during the launch of Mars Probe 7, he became head of the new Space Security Department. Carrington plotted with Sir James Quinlan to capture three of the aliens. While Quinlan wanted the political coup of being involved in "first contact" with alien ambassadors, Carrington was using him for his own agenda: he believed the aliens were a threat to Earth and wanted to convince the world to go to war against them, believing this to be his "moral duty". Using loyal members of his regiment, a criminal gang headed by Reegan, and the scientists Bruno Taltalian and Lennox, he was able to force the aliens into attacking government installations (and to kill Quinlan to cover his tracks).

Carrington became more obviously unhinged as the conspiracy went on, with Ralph Cornish noticing he was insane after the United Nations Security Council decided not to launch a first-strike on the aliens. He eventually arrested UNIT because he thought they were working with the aliens and took over Space Control, planning to expose the aliens on live television to terrify the general public. He was stopped after the Third Doctor, Brigadier Lethbridge-Stewart and the newly-released UNIT troops arrived to rescue the aliens. The fight went out of him when he realised he had lost, and he was arrested.

The Doctor recognised that Carrington was unhinged and gently told him that he understood why Carrington had done what he did. (TV: The Ambassadors of Death)

Behind the scenes Edit

The Mars Probe missions are ignored by the Doctor Who television story The Waters of Mars, which referred to the human colony founded in 2058 as being made up of the "very first humans on Mars". Further complicating matters, an on-screen obituary in The Waters of Mars mentions that the captain of the Bowie Base One colony, Adelaide Brooke, along with two other unidentified astronauts, had already landed on Mars when Adelaide was 42 in the year 2041.

In the novelisation, his full name is given as Charles Carrington.
