“For the performance of this agreement, hostages were given to the English, and a messenger despatched to acquaint Baliol that a truce had been obtained; which he was instructed to say, was effected entirely by the dexterity of Siward, and his personal influence with a number of the English nobles. Baliol was also advised to advance and attack the English army while “at meat,” and that, at the same time, Siward would make a sally to assist him in destroying the enemy--which the messenger spoke of as a matter of certainty, and moreover counselled Baliol to proceed immediately afterwards and plunder Northumberland. “On the third day, Siward, from the battlements of Dunbar, discovered the Scottish army rapidly approaching towards him; he therefore hastily sought the English head-quarters, and proffered to go personally and retard the advance of the Scots till the expiry of the time stipulated for by the agreement. The English, however, were not inclined to believe that he would carry his treason quite so far, and refused him permission to proceed to the Scottish lines.[99] “Siward, on being relieved from his confinement in the Tower, rose high in the confidence of Edward. On 26th September 1298, 7th May and 16th June 1299, he was summoned, by the title “Baron,” to serve in Scotland. His name appears on several occasions in the Wardrobe Account of 28th Edward I. In that year he received 41_l._ 5s. for the services of himself and his followers in the garrison of Lochmaben. Also an allowance of 2_l._ 13s. 4d. for the value of a horse killed at Kirkcudbright; eight merks for a winter dress (robe); and the like sum appears to have been paid to him for a summer dress. In the same year he was again summoned for the Scottish war, and also in 1301. He was made sheriff of Dumfries-shire in 1305, and was also aiding in the suppression of Robert Bruce in 1308; in which year he was appointed to the charge of a district in Galloway, under Edward II. In 1309 he was governor or constable of Dumfries, and is supposed to have died in 1310. By his wife Mary he had two sons, Richard and John. They both attained the age of manhood; and John, in particular, appears to have followed the crooked anti-patriotic policy of his father. He accompanied the Earl of Pembroke in his invasion of Fife, as has been already mentioned, and was rewarded by Edward with an appointment as Governor of Perth. Little appears to have been known of Richard. He was married to Elizabeth ---- in 1296. The arms of Siward, as has been already noticed, were sable, a cross fleury, argent.
