60

In 60, the Fourth Doctor and his companion Leela visited Norfolk, where they met Boudica, the Queen of the Iceni, during her revolt against the occupying Roman forces in Britannia. In order to prevent Boudica from severing his head, Leela told her that the Doctor was a prophet who foresaw her defeat at the hands of the Romans. The Doctor told her that the forces at the Roman capital Camulodunum were a decoy and Roman governor Suetonius Paulinus stationed an army to the north and intended to attack Boudica's army while it was ransacking Camulodunum.
However, this was not the case. There was no army to the north. According to established history, after the burning of Camolundunum, which would later become Colchester, Boudica marched to Londinium and slaughtered almost everyone in the city including the old, the weak and the infirm. She was eventually defeated in a field in the middle of England which no one has ever been able to identify. There were no survivors. Instead of allowing the Romans to execute her, Boudica killed her daughters before killing herself. The Roman occupation of Britain continued for another 350 years. (AUDIO: The Wrath of the Iceni)
Gaius Calaphilus was among the soldiers who fought "Boudica's wretched Iceni." (PROSE: Byzantium!)
The renegade Time Lady Iris Wildthyme claimed that she had also been present at the Siege of Colchester. (AUDIO: The Elixir of Doom)
Marcus Aurelius Gallius and his centurions were en route to Colchester to attack Boudica when they were captured by a time eddy and placed in 1959 London. The Ninth Doctor later aborted these events by stopping the eddies in the past. (AUDIO: Sphere of Freedom)
