Read it through once

The English had built a fence of strong fortresses called bastilles around Orleans—fortresses which closed all the gates of the city but one. To the French generals the idea of trying to fight their way past those fortresses and lead the army into Orleans was preposterous; they believed that the result would be the army’s destruction. One may not doubt that their opinion was militarily sound—no, would have been, but for one circumstance which they overlooked. That was this: the English soldiers were in a demoralized condition of superstitious terror; they had become satisfied that the Maid was in league with Satan. By reason of this a good deal of their courage had oozed out and vanished. On the other hand, the Maid’s soldiers were full of courage, enthusiasm, and zeal.
