In the seventh week after Easter (4–10 May 878), around Whitsuntide, Alfred rode to Egbert's Stone east of Selwood where he was met by "all the people of Somerset and of Wiltshire and of that part of Hampshire which is on this side of the sea (that is, west of Southampton Water), and they rejoiced to see him". Alfred's emergence from his marshland stronghold was part of a carefully planned offensive that entailed raising the fyrds of three shires. This meant not only that the king had retained the loyalty of ealdormen, royal reeves and king's thegns, who were charged with levying and leading these forces, but that they had maintained their positions of authority in these localities well enough to answer his summons to war. Alfred's actions also suggest a system of scouts and messengers.
