"It'll be a hard nut to crack," observed the merry Jack, casting his eye up at the defences; "but I suppose we'll do it." "We must," declared Tom with emphasis. "Anyway, I've got to get inside the place and unravel this mystery. There's father and Don Juan to find and release, and then there's that rascal who took them." But would Tom, or indeed any of our men, ever get within this terribly grim fortress? It seemed unlikely enough, viewing the defences, and we may declare here and now that before our hero was to set foot within the place he was to take part in fighting of the very fiercest. CHAPTER XIV One of the Forlorn Hope "A terribly hard nut to crack," observed Jack, for perhaps the twentieth time, as he and Tom sat their horses on a ridge above Badajoz, and looked down upon the fortress. "It'll be interesting to see how Wellington sets about the matter. Suppose there'll be a tremendous cannonade, and then an assault. Wish we were going to be in it." "I mean to, whatever happens," came from our hero, who was staring down at the fortress, as if he wished to guess in which house his father and Don Juan were imprisoned. "As to how it'll be done, there's no saying; for I've never witnessed a siege before. But apparently the sappers and miners dig their way toward the fortress, erecting batteries as they go, till they are so close that our guns can batter down the walls. Then comes the grand assault. I can imagine that that is a terrific business. Well, let's ride round the place and see what's happening. There's very little else for us to do just now, and we can leave the men with Alfonso."
