Battle of Passchendaele

The Battle of Passchendaele, also known as the Third Battle of Ypres, was a major battle of World War I.

On 7 June, 1917, at 3:10 AM, nearly a million pounds of British mines detonated. The Fourth Doctor stated that the explosion was heard in London. (AUDIO: The Haunting of Malkin Place)

The First Doctor was on the field of battle and later regarded it as an awful event. (PROSE: Byzantium!) The Fifth Doctor listed Passchendaele as one of the many battlefields he had walked through. (PROSE: The King of Terror) Charley Pollard's uncle Jacques lost an arm during the battle. (AUDIO: The Next Life)

Behind the scenes
The Battle of Passchendaele is also known as the Third Battle of Ypres as a result of the two towns being very close to each other. Fighting at Ypres during World War I is mentioned in PROSE: Illegal Alien but the real world connections between the battles at Ypres and Passchendaele have yet to be referenced in the DWU.
