John was succeeded by his son Henry, then a boy of nine. The death of their enemy brought back the Barons to their allegiance: forty of them at once went over to the young King, the rest followed one by one. Louis was left almost alone in London with his Frenchmen. The pride and arrogance of the foreigners went far to disgust the English and inclined them to return to their loyalty. After the defeat at Lincoln, Louis found himself blockaded within the City walls, unable to get out, and, unless relief came, likely to be starved into submission. This is the second instance in history of the City being blockaded both by land and sea: the first being that siege in which Cnut brought his ships round the Bridge. The Thames was closed: the roads were closed: no provisions could be brought into the City by river or by road. And when a fleet, sent by the French King to the assistance of his son, was defeated by Hubert de Burgh off Dover, whatever chance the Prince might have had on his arrival was gone. Louis made terms. He stipulated for an amnesty for the citizens of London: on the strength of that amnesty, or as the price of it, he borrowed 5000 marks (or perhaps £1000) of them and so returned to France. The young King was received by the citizens with the usual demonstrations of exuberant joy. Had they known what a terrible half-century awaited them, they would have been less demonstrative. A Parliament was held at London as soon as Louis had gone: the care of the young King, whose mother had already married again, was committed to the Bishop of Winchester. The new buildings at Westminster were commenced by the Bishop of Winchester as one of the first of Henry’s acts.
