The city of Orleans itself was on the north side of the Loire, but its suburbs extended far on the southern side, and a strong bridge connected them with the town. A fortification which in modern military phrase would be termed a tete-du-pont, defended the bridge-head on the southern side, and two towers, called the Tourelles, were built on the bridge itself, where it rested on an island at a little distance from the tete-du-pont. Indeed, the solid masonry of the bridge terminated at the Tourelles; and the communication thence with the tete-du-pont on the southern shore was by means of a drawbridge. The Tourelles and the tete-du-pont formed together a strong fortified post, capable of containing a garrison of considerable strength; and so long as this was in possession of the Orleannais, they could communicate freely with the southern provinces, the inhabitants of which, like the Orleannais themselves, supported the cause of their Dauphin against the foreigners. Lord Salisbury rightly judged the capture of the Tourelles to be the most material step towards the reduction of the city itself. Accordingly he directed his principal operations against this post, and after some severe repulses, he carried the Tourelles by storm, on the 23d of October. The French, however, broke down the part of the bridge which was nearest to the north bank and thus rendered a direct assault from the Tourelles upon the city impossible. But the possession of this post enabled the English to distress the town greatly by a battery of cannon which they planted there, and which commanded some of the principal streets.
