Project Crimean Eviction

Project Crimean Eviction was a plan, created by the Thirteenth Doctor during the alternate Crimean War.

The plan used Sontaran's need of a rest cycle of 7.5 minutes, every 27 hours, when they all went back into their ships stationed in the base camp. During the rest their protective armoured suits were being refilled with chemicals and nutrients from Sontar. The Doctor planned to empty their ships of those supplies, forcing a retreat out of the Crimea back to the 21st century where Dan Lewis could deal with them.

Together with Mary Seacole and Lieutenant General Logan they succesfully completed the plan. Commander Skaak decided to make a strategic withdrawal, promising to return. However, to the Doctor's anger and disappointment, Logan fired a pile of gunpowder barrels, exploding retreating ships. (TV: War of the Sontarans)
