The general outlook, when Alfred was chosen king of the English in succession to his brother, must have been terrible indeed. The Danes, already masters of Northumbria, East Anglia, and Mercia, were in the very heart of the kingdom of Wessex; and, notwithstanding the many battles Ethelred had fought with them, they were in possession of several towns; and not only maintained their position in the island, but had reason to hope they should soon complete the conquest of it. The new monarch had only been a month on the throne, when he found himself obliged to take the field against these formidable enemies, who had advanced as far as Wilton, whither he marched to attack them. Victory for some time inclined to his side, then suddenly changed in favour of the Danes; but Alfred's loss was not so considerable as to make him despair, though the victory certainly belonged to the enemy. He laboured incessantly to put his army in condition to give them battle again, before they should be reinforced; they were astonished at his expedition, and, though victorious, sued for peace, finding themselves unable to continue the war. As they offered to march out of his dominions, on condition he would not molest them in any other part of England, Alfred accepted their offer, and gained by this treaty time to prepare against a new invasion. The Danes, quitting Wessex, retired to London, which they had taken during the late war. Ingvar was gone back to Denmark, having left the command of the army to his brother Hubba, who, being prevented from attacking Wessex, turned his arms against Mercia. Burhred, its king, knowing he was unable to resist, since Alfred was bound not to send him any succours, thought it his wisest course to buy off the Danes with a sum of money, and save his country from their depredations. Upon the receipt of the money, they marched towards Northumbria, designing to take up their quarters with their countrymen; but their provisions running short, in consequence of the devastations they themselves had made there, they were under the necessity of returning into Mercia.
