While ascribing the expulsion of the English from France to political rather than strategical reasons, we must not forget that the professional officers of the fifteenth century had at last discovered a method of minimizing the ascendancy of the English soldiery. When they found the invaders drawn up in a good defensive position, they invariably refrained from attacking them. There was no object in making the troops a target to be riddled with arrows, when success was almost impossible. Accordingly the French victories of the second quarter of the century will be found to have resulted in most cases from attacking an English army at a moment when it was on the march or in some other position which rendered it impossible for an order of battle to be rapidly formed. Patay is a fair example of a conflict of this description; the battle was lost because Talbot when attacked was not immediately ready. Expecting to see the whole French army arrive on the field and draw itself up in battle array, he paid no attention to the mere vanguard which was before him, and commenced falling back on the village of Patay, where he intended to form his line. La Hire, however, without waiting for the main-body to come up, attacked the retreating columns, and forced his way among them ‘before the archers had time to fix their stakes[111].’ The superiority of the bow to the lance depended on the ability of the bearer of the missile weapon to keep his enemy at a distance. If once, by any accident, the cavalry got among their opponents, a mere _mêlée_ ensued, and numbers and weight carried the day. Such was the case on this occasion: La Hire having succeeded in closing, the battle resolved itself into a hand-to-hand struggle, and when the main-body of the French came up, the English were overpowered by numerical superiority. Such were the usual tactical causes of English defeats in the fifteenth century.
The fall of the empire which Henry V had established in France was therefore due, from the military point of view, to the inadequacy of a purely defensive system to meet all the vicissitudes of a series of campaigns. The commanders who had received the tradition of Agincourt and Poictiers disliked assuming the offensive. Accustomed to win success by receiving the enemy’s attack on a carefully chosen ground, and after deliberate preparations, they frequently failed when opposed to officers who refrained on principle from assailing a position, but were continually appearing when least expected. In the open field or on the march, in camp or the town, the English were always liable to a sudden onslaught. They were too good soldiers to be demoralized, but lost the old confidence which had distinguished them in the days when the French still persisted in keeping up their ancient feudal tactics.
