communication with the Danes of York for the surrender of that city, too, when she died suddenly in her royal town of Tamworth, in the year 918. Meanwhile Eadward had been pushing forward his own boundary in the east, building _burhs_ at Hertford and Witham, and endeavouring to subjugate the Danish league in Bedford, Huntingdon, and Northampton. In 915, Thurketel, the jarl of Bedford, "sought him for lord," and Eadward afterwards built a _burh_ there also. On his sister's death, he annexed all her territories, and then, in a fierce and long doubtful struggle, reconquered not only Huntingdon and Northampton but East Anglia as well. The Christian English hailed him as a deliverer. Next, he turned on Stamford, the Danish capital of the Fens, and on Nottingham, the stronghold of the Southumbrian host. In both towns he erected _burhs_. These successes once more placed the West Saxon king in the foremost position amongst the many rulers of Britain. The smaller principalities, unable to hold their own against the Scandinavians, began spontaneously to rally round Eadward as their leader and suzerain. In the same year with the conquest of Stamford, "the kings of the North Welsh, Howel, and Cledauc, and Jeothwel, and all the North Welsh kin, sought him for lord." In 923, Eadward pushed further northward, and sent a Mercian host to conquer "Manchester in Northumbria," and fortify and man it. A line of twenty fortresses now girdled the English frontier, from Colchester, through Bedford and Nottingham, to Manchester and Chester. Next year, Eadward himself, now immediate king of all England south of Humber, attacked the last remaining Danish kingdom, Northumbria, throwing a bridge across the Trent at Nottingham, and marching against Bakewell in Peakland, where again he built a _burh_. The new tactics were too fine for the rough and ready Danish leaders. Before Eadward reached York, the entire North submitted without a blow. "The king of Scots, and all the Scottish kin, and Ragnald [Danish king of York], and the sons of Eadulf [English kings of Bamborough], and all who dwell in Northumbria, as well English as Danes and Northmen and others, and also the king of the Strathclyde Welsh and all the Strathclyde Welsh, sought him for father and for lord." This was in 924. Next year, Eadward "rex invictus" died, over-lord of all Britain from sea to sea, while the whole country south of the Humber, save only Wales and Cornwall, was now practically united into a single kingdom of England.
