Fall of Arcadia
The Fall of Arcadia was a battle fought on the last day of the Last Great Time War.
The city of Arcadia was thought to be "the safest place on Gallifrey", because it was protected by 400 sky trenches. Despite this, a massive Dalek force of millions of Dalek fighter pods and Dalek flying saucers managed to penetrate the trenches, destroying the once proud city, while the Time Lord soldiers fought back in desperation. (TV: The Last Day, The Day of the Doctor)
The War Doctor was at Arcadia, fighting on the front lines. Witnessing the devastation, he blasted the words "NO MORE" into a wall as a message to both the Daleks and the Time Lords, and departed to steal the Moment with the intention of ending the war once and for all. (TV: The Day of the Doctor)
