7N. Doctor Who - Battlefield

The TARDIS lands near Carbury, and the Doctor and Ace hitch a lift with the local archaeologist who is concerned about a UNIT nuclear convoy that has become stranded near Vortigen's Lake. The U.N.I.T. patrol, commanded by Brigadier Winifred Bambera, is too busy to notice the Doctor and Ace entered the area with old pass cards.

Underneath the lake is an ancient spaceship where the remains of King Arthur are rumoured to lie, along with his sword Excalibur. A group of warriors from a parallel dimension come to retrieve the sword. They all recognise the Doctor - as Merlin the magician, even to the point of knowing that he had a ship of time whose dimensions within defy those without.

Battles break out between an armoured knight and a group of Morgaine's troops and between U.N.I.T. Brigadier Lethbridge-Stewart, learning that the Doctor is involved, comes out of retirement. As the situation gets worse, the Doctor and Ace find their way into the spaceship, and while Ace escapes, the Doctor is attacked, only to be rescued by Brigadier Lethbridge-Stewart.

Morgaine is so desperate to have Excalibur that she unleashes the Destroyer of Worlds. Beofre the final confrontation Brigadier Lethbridge-Stewart knocks the Doctor unconscious and shoots silver bullets into the destroyer, annihilating it.

No studio details are available



  • Episode 1: In the TARDIS scene, look closely at the roundels - you can see the occasional 'crease', as if the wall was just a sheet hung up behind the console. (The TARDIS walls prop had been destroyed because of Andrew Cartmel's insistence that no more scenes were to be set inside the TARDIS)


  • The episode number for Part One is in the centre of the screen, instead of near the bottom as with other McCoy episodes.
