St. Edmund knew they would sooner or later invade his kingdom too. So he set to work to prepare for them. His chief way of doing this was to win the loyalty of all his subjects, so that if there was war he knew they would all rally round him. He made wise laws, and he was so fair to all, and so ready to listen to the poor and oppressed and help them, that soon everyone in the kingdom loved the young King and would do anything for him. They could see that God was with him, and they could not help feeling that in serving the humblest of his subjects he felt that it was Christ Himself that he served. St. Edmund had, of course, prepared his army and had thrown up defences to try and keep the enemy out as long as possible. You can still see one of his great earthworks running from Newmarket to the Fen country. For hundreds of years it was called "Edmund's Dyke." He placed scouts and outposts all round his borders, and prepared in every way he could. At last the day came when the country people came running into the towns in terror. They had seen along the borders huge, fierce men, with flashing eyes and long red hair and beards. Their leather tunics were stained dark with blood. Huge round shields were slung across their backs; they were armed with spears, bows, clubs, and knives, and they shouted to one another in a strange language. St. Edmund's scouts came running in to say that the Danes were collecting in great crowds on the frontiers. Soon they began creeping in at every point, burning houses and churches, and killing people, especially the Christians. Though it was an almost hopeless job, St. Edmund led his brave army forward, and whenever it was possible he engaged the enemy in battles and drove them out. The Danes had never before been so powerfully resisted, and thousands of them were killed. There's not time now to tell you all of the thrilling adventures St. Edmund had at this time, and of his wonderful escapes from the Danes. Anyhow, the Danes were so much weakened that they asked for peace, and after spending the winter in a great camp at Thetford, they sailed away, full of rage and hatred and desire for revenge. _A Cowardly Plot._ For a time there was peace, and then a sad thing happened.
