Accordingly, the siege was laid in due form. Three hundred of the very pick of the corps entered the Lines of the fortress, while others stretched themselves like a wall of circumvallation around the entrenched camp. The enemy were known to be there. The invading and advancing force came now and then upon native fires, still smouldering. They saw chippings from newly formed spears and waddies.
