There is no evidence that Edward had formed any coherent plan of operations. Able tactician as he showed himself at Crecy, he was no strategist; indeed no one in that age had any idea of strategical combinations, though of course it is easy after the event to see that a particular direction given to an army was or was not judicious from this point of view. This invasion of France might have been an extremely brilliant stroke. The English command of the sea made it feasible to land almost anywhere; the main French army was engaged in the south-west: there were no preparations for attempting to meet invasion anywhere else. Had Edward landed near the mouth of the Seine, at the nearest point to the capital, and marched straight on Paris, he would have had the king of France almost at his mercy, for Paris might have been in his hands before the duke of Normandy could come to its rescue. Instead of this, Edward landed at the extremity of the Cotentin peninsula, and then marched in a leisurely way through Normandy, capturing and plundering town after town, there being virtually no resistance. The absolute vagueness of his intentions may be gathered from his having sent away his fleet, laden with the booty of the Norman towns, thus depriving himself of the means of retreat in case of need. If Froissart is to be believed, he had already determined to march on Calais and attempt to seize it; but if so, it is still more difficult to explain his having landed in the Cotentin, Calais being within a march or two of Flanders, where if he had not met with much support he would have at least found a friendly reception. The only thing which looks as if he really meant to go towards Calais is that having reached Louviers, he seems to have marched some way down the Seine again towards Rouen; but this may have been in the hope of being able to plunder the capital of Normandy. The French meanwhile had broken down all the bridges on the Seine, which can only have been in order to prevent the English from extending their ravages to the right bank of the Seine, as it was obvious that they could reach the coast as easily on one side as on the other. Whatever may have been his original plan, or want of one, Edward, unable to cross the Seine in Normandy, did what he ought to have done weeks before, and marched up the left bank towards Paris. The king of France had used the breathing time unwisely allowed him to collect an army, which is said to have amounted to 100,000 men. Why he made no attempt to interfere with Edward earlier is a mystery. The English king marched unopposed to Poissy, a few miles below Paris, and there amused himself, while the bridge was being rebuilt, in ravaging the country to the very gates of the capital; he no doubt knew that the city was by this time full of soldiers, and therefore not open to attack. On August 16 the bridge was finished, and Edward crossed the Seine, his advanced guard
