21 (it should have been 22 but one didn't turn up) amateur tennis players, all men, competed in the first ever tournament held by the All England Croquet and Lawn Tennis Club for the first time on this day.

The final of this first tournament was held on 19th July. It was between William Marshall, a Cambridge tennis "Blue" against W. Spencer Gore, an Old Harrovian racket player. The 27 year-old Gore won 6-1, 6-2, 6-4.

In what was a shocking breach of security, a man, Michael Fagan, 31, managed to get into the Queen's bedroom to 'have a chat with her' at 7:15am by climbing up an outside drainpipe.

The Queen was only able to summon help when Fagan asked for a cigarette - the Queen then called for a footman who restrained him until the police arrived.

In what was kept a complete secret until 30 years after the Second World War, one of the most important British anti-Nazi groups broke what the Nazi's believed to be a completely unbreakable code, the Enigma code.

The Nazi's used Enigma to encode transmissions which included details of troop movements between operating units. By being able to decode Enigma the Brits were able to tell what the Germans were doing.
