But no sooner had Edward gone, than the King of Scotland invaded England. Philippa did not spend long in wondering what was to be done--she went quickly to Newcastle, where she awaited the English army. When the King of Scotland heard she was there, he sent to say that he was ready to fight! Philippa sent back word, that she was ready too; adding, "My barons will risk their lives for the realm of my lord the king!" The queen's army drew up at Neville's Cross, and Philippa, on a white charger, so runs the story, was among them. She begged them to do their duty, and to defend the honour of the king; then leaving them to the protection of God, she rode away. She would not stop to fight; her nature was too womanly to stay and see the carnage which was going to take place; she had done all a great queen could do by cheering and encouraging her men; now she would go and pray for victory while the battle raged. When she heard it was over, she mounted her white horse and rode again to the battle-field, where she heard that not only had a victory been won, but the King of Scotland had been taken prisoner. He was taken on a tall black war-horse through the streets of London, and put in the Tower. The next day Philippa sailed for Calais, and her royal husband held a grand court to welcome his victorious queen. The terrible siege of Calais was going on; the French had defended it bravely, till at last they were so much reduced by famine that they were obliged to surrender. Everything was eaten, even the cats, dogs, and horses; there was no corn, no wine, and the unhappy people were fast dying. So the governor of Calais came to ask Edward on what terms they could surrender. Edward was very angry at having been kept waiting so long, and refused to spare the people unless the six chief men of Calais would come out bareheaded and bare-footed, with ropes round their necks and the keys of Calais in their hands, ready to die for the rest of the people. The governor returned sad and sick at heart, and calling the people together he gave them the king's message. There was silence for a moment among the feeble few. Then the hero Eustace de St. Pierre cried: "Oh! never be it said, That the loyal hearts of Calais To die could be afraid! I will be the first, I will willingly give myself up to the mercy of the King of England." Then five others followed his brave example, and the willing captives came before the angry king. They knelt and pleaded for mercy. But in vain. In vain the lords around him begged him to restrain his anger,--he only thundered: "Strike off their heads, each man of them shall die; I will have it so!" Then gentle Philippa stepped forth and knelt at the feet of her royal husband: "My loving lord and husband," she cried, "I have crossed the stormy sea with great peril to come to you--I have been faithful to you all our wedded life--do not deny my request, but, as a proof of your love to me, grant me the lives of these six men!"
