In 1051, Count Eustace of Boulogne, on his return from a visit to King Eadwarde, treated the people of Dover with great insolence, who fell upon him and his followers, and gave them a deservedly severe chastisement. Eustace demanded redress from the King, who commanded Earl Godwine to punish the Dover people, who, finding that Eustace had been the aggressor, asked that they might be heard in their defence, to which the King would not listen; then Godwine assumed a higher tone, and demanded the surrender of the Count to answer for his insolence. This enraged the King, who summoned Siward and Leofric to render assistance against the hostile designs of Godwine. They came to Gloucester, where a compromise was effected; but at a subsequent gemôt, held in London, Godwine and his family were banished. The most creditable military effort of the many in which his sword had been drawn, and that which redounded the most to his glory, was the last of his life. In 1054, he was sent by King Eadwarde in command of an expedition into Scotland against the usurper, Macbeth, in favour of the young Prince, Malcolm Canmore, son of the murdered King Duncan. He was now the father of two sons by his first wife--Æthelfleda--Osbert, now approaching manhood, and Waltheof, a boy, some years younger. The former he took with him to Scotland, to initiate him in the then deemed glorious art of war; and a brave young fellow he proved himself to be, a worthy scion of the old stock. Siward attacked Scotland by land and sea, met the usurper and defeated him in a pitched battle, after which he caused Malcolm to be proclaimed King. It is sometimes stated that Macbeth was slain in the battle, which was not the case, as he escaped and held out for three years, maintaining a desultory series of fights with Malcolm, but was eventually slain in 1057. His son Osbert fell in the battle, fighting bravely, and when the news was brought to him, he eagerly inquired if his wounds were in front, and when told they were, said that he could not but rejoice, such a death being worthy of one sprung from his loins. Shakspeare, not always true to history, in his tragedy of "Macbeth" thus gives the death of "Young Siward," as he calls Osbert:--He meets with Macbeth on the field, and, after some bandying of words, they fight, and Macbeth falls, after which Osbert rushes into the thick of the fight, and falls himself. When Siward is told that all his son's wounds are in front, he exclaims-- "Why, then, God's soldier is he! Had I as many sons as I have hairs, I would not wish them to a fairer death: And so his knell is tolled." Prince Malcolm observes-- "He's worth more sorrow, And that I'll spend for him." To which Siward replies-- "He's worth no more. They say he parted well, and paid his score, And so God be with him."
