But there immediately occurred an incident which required that Edward should either openly declare his pretensions, or forever renounce and abjure them.

He was summoned to do homage for Guienne: Philip was preparing to compel him by force of arms: that country was in a very bad state of defence: and the forfeiture of so rich an inheritance was, by the feudal law, the immediate consequence of his refusing or declining to perform the duty of a vassal.

Edward therefore thought it prudent to submit to present necessity: he went over to Amiens, did homage to Philip, and as there had arisen some controversy concerning the terms of this submission, he afterwards sent over a formal deed, in which he acknowledged that he owed liege homage to France;[**] which was in effect ratifying, and that in the strongest terms, Philip's title to the crown of that kingdom.

His own claim indeed was so unreasonable, and so thoroughly disavowed by the whole French nation, that to insist on it was no better than pretending to the violent conquest of the kingdom; and it is probable that he would never have further thought of it, had it not been for some incidents which excited an animosity between the monarchs.
