The Battle of Tourcoing is one of those actions upon which European history in general is somewhat confused, and English history, in particular, ignorant. That British troops formed part of those who suffered defeat, and that a British commander, the Duke of York, was the chief figure in the reverse, affords no explanation; for the almost exactly parallel case of Fontenoy-in which another royal duke, also the son of the reigning King of England, also very young, also an excellent general officer, and also in command was defeated-is among the most familiar of actions in this country.
