Dunkirk

Dunkirk was a port city in northern France.

During World War II, from late May to early June 1940, thousands of British Army soldiers were evacuated from the area in Operation Dynamo, after they had been cut off from the rest of the army by the German advance.

Although the German army could have easily destroyed the British forces, the Seventh Doctor had convinced Adolf Hitler, who was unstable and disoriented after the Timewyrm had been banished from his mind, to not advance on Dunkirk. (PROSE: Timewyrm: Exodus)

The First Doctor was present at Dunkirk, (PROSE: Just War, PROSE: Byzantium!) as was the Eighth Doctor. (AUDIO: Fugitives)

The Tenth Doctor and Donna Noble prevented a Nemonite from taking possession of those involved in the Dunkirk evacuation. (AUDIO: The Nemonite Invasion)

The Dunkirk evacuations left British Prime Minister Winston Churchill dispirited. The Doctor spoke to him afterward and was able to lift his mood and convinced him to keep Britain in the war in defiance of Nazi Germany. (AUDIO: The Ultimate Adventure)

In 2009, the Torchwood Three team found the body of a sailor from the Dunkirk evacuation washed up on a beach. (AUDIO: The Sin Eaters)

In an alternate timeline in which Hitler kept the power of the Timewyrm, the Germans advanced on Dunkirk and totally defeated the British Army. (PROSE: Timewyrm: Exodus)

When Atmospheric Omission Systems polluted the Earth's air, people in America were forced to take boats out into the Atlantic Ocean in a scene likened to Dunkirk. (TV: The Poison Sky)
