Edgar ran towards the breach again, and on the way came upon his two companions running along, with the marines and blue-jackets after them. Fortune, however, had done more for the town than its defenders. Led by an officer with sixteen sappers, and followed by twenty-five grenadiers, the French party prepared to mount to the assault. Their orders were to mount the breach and hold it, and the moment this was done the main body of the storming party were at once to follow. But they met with an unexpected obstacle. Instead of finding, as they had expected, merely a shallow ditch, they found themselves at the edge of a counterscarp, the wall being fifteen feet in depth, with a regular moat filled with water between them and the foot of the breach.
