The Dalek-Movellan War was a massive war fought between the mutant Daleks and the android Movellans which lasted for centuries. Each side was lead by battle-computers to calculate the enemy's moves. However, each computer could predict the other's moves so well that they were locked in a stalemate. Hundreds of Dalek battlecrusiers and Movellan battlecruisers flew with each other for hundreds of years without firing one shot as a result of this.
