The Political History of England, Vol II, George Burton Adams Longmans Green and Co, 1905, Ch XXI, p431:
 "It was about July first that Louis set out to raise the siege of La Roche-au-Moine, and on the 27th the decisive battle of Bouvines was fought in the north before John had resolved on his next move. The coalition, on which John had laboured so long and from which he hoped so much, was at last in the field. The emperor Otto IV, the Counts of Flanders, Bologne, Holland, Brabant, and Limburg, the Duke of Lorraine, and others, each from motives of his own, had joined their forces with the English under the Earl of Salisbury, to overthrow the king of France. To oppose this combination Philip had only his vassals of northern France, without foreign allies and with a part of his force detached to watch the movements of the English king on the Loire. The odds seemed to be decidedly against him, but the allies, attacking at a disadvantage the French army which they believed in retreat, were totally defeated near Bouvines. The Earl of Salisbury and the Counts of Flanders and Boulogne with many others were taken prisoners, and the triumph of Philip was as complete as his danger had been great..."
