"Very well. All will be cleared up at headquarters. Of course, you will accompany us." "At any rate," replied he, anxious to back out, "I hope to have the pleasure of meeting you there." "No, no," said I; "you go with us." By this time he was decidedly in a fidget, and began to hang behind. Just then we came suddenly to a lane, branching off to the right. This was probably the very direction he had wished me to take; though whether it really led to a ford over the Adour, or to what it led, was a different question. Before I was aware of his design, he turned sharp in that direction; and, when I looked after him, he was already some distance down the lane, digging his heels into the old poster's sides. This operation had put the gay old stager into something as much like a gallop as you can hope to get out of a French post-horse. He was off! Ah! our cavalry had left us too soon. I looked round, and shouted "Fraser!" Fraser, prepared for my order, and anxious to have all ready for executing it, had three men marching at hand, with loaded firelocks. Three balls whistled down the lane. But it was a waste of his Majesty's powder and shot; the fugitive escaped unhurt. Not so, though, the lively old post-horse. His screwed tail, his stradding hind-legs, and his action--for a moment prancing, not progressive--gave evident indications that the luckless beast had not got off so easily as his rider. Then, in an agony of apprehension lest his scutcheon should receive a second totem, he plunged forward again at his previous rate, and soon disappeared down the lane. Pursuit was out of the question, for Sancho's best pace was an up-and-down; even a French horse was too fast for a French pony: so both horse and horseman got off. My first care, on reaching headquarters, was to make inquiry respecting this new member of our department. You will hardly need to be informed, that there was no such person belonging to us. The only question was, how did he get the uniform coat? It certainly was not that of the corresponding department of the French service, which not only rejoiced in the appropriate embellishment of a key embroidered on the collar, but differed in other respects from ours. Some said he must have procured the coat at Lisbon. Some said he had got it made for the occasion. A gentleman of the Commissariat suggested that he had picked up a coat at headquarters, cast off when some of us had been promoted. But the worst of it was, our department couldn't recollect when any such cheering event had taken place.
