Their garrisons, absurdly small, were prisoners in the country they had conquered.

The English had long teeth, but a pike cannot swallow an ox.

That they were too few and that France was too big had been plainly seen after Crecy and after Poitiers.

Then, after Verneuil, during the troubled reign of a child, weakened by civil discord, lacking men and money, and bound to keep in subjection the countries of Wales, Ireland, and Scotland, were they likely to succeed better?
In 1428, they were but a handful in France, and to maintain themselves there they depended on the help of the Duke of Burgundy, who henceforth deserted them and wished them every possible harm.
They lacked means alike for the capture of new provinces and the pacification of those they had already conquered.

The very character of the sovereignty their princes claimed, the nature of the rights they asserted, which were founded on institutions common to the two countries, rendered the organisation of their conquest difficult without the consent and even, one may say, without the loyal concurrence and friendship of the conquered.
