Historical background to the scene: The one-year siege of Calais ended in 1347 with its conquest by the English. According to tradition, Edward wanted to hang six citizens out of anger over the long siege. As a result, pregnant Queen Philippa knelt before him to ask for mercy, and Edward spared them.
