The Battle of the River Plate became famous partly because it happened so early in World War II. Britain's experience in World War I had led the public to expect a surface-raider battle in which Royal Navy cruisers would engage the enemy. People also expected to hear about that action, so the early engagement delivered a morale boost. It gave visible proof of the Navy's repeated promise to protect maritime trade. In that sense, the battle was almost more important than Graf Spee's entire preceding cruise. Understanding the battle still requires an account of the cruise that led to it.
