Okay, so the main spoiler in this one isn't THAT much of a spoiler in my mind, but it still is a spoiler.


If you know anything about the Boston Massacre, only five people died. It wasn't a planned attack, but the soldiers got scared. There was literally a mob circling them possibly with torches and pitchforks. The soldiers were already scared, so when they heard someone yell 'FIRE', they shot. It wasn't an order from their boss to fire, and nobody really knows who yelled it.

There might have been an actual fire, or maybe someone just shouted that so that they would be able to use the event as anti-British propaganda.


Now that you know the real history, here's where the spoiler comes in. The TARDIS blows up when the Doctor, Alexis, K-9, and River Song just happen to be in the same time (and place) zone of the Boston Massacre. They run out of the TARDIS, and the Doctor yells, "FIRE!" That's how the Boston Massacre occurred you know, the Doctor blew up the TARDIS at exactly the wrong time.
