[CHAPTER XVII]
A Clue at Last

Those 40,000 victorious men of Wellington's great army now had their backs to the Portuguese frontier and were marching gaily on Madrid. Away in front a half-battalion of infantry watched for the French and found no trace of them. The guard in rear had an easy time of it, for attack was not to be feared from that quarter; while the cavalry patrols on either flank reported a country clear of all but peasants. As for the road itself, it was littered with carts of every description, not the motor lorries which to-day have achieved a triumph, making light of the task of hauling the stores and impedimenta of an army, but with mule carts in endless array, and four-wheeled and two-wheeled vehicles with their teams of mules and their gaudily-hatted drivers.

"Of all the aggravating, lazy beggars these are the worst I ever set eyes on," growled Jack Barwood, in command now of Tom's composite corps of Portuguese and Spanish; for that young fellow himself, together with Alfonso his cousin, had departed on special service. And didn't the great Jack give himself airs! Riding at the head of the corps he looked about him as does a conqueror. And these muleteers came in for his displeasure.

"Straggling all over the road as usual. How's one to pass here?" he demanded of Andrews, who was marching beside him, and pointing to a batch of vehicles wedged in a rocky part of the road where a detour was almost impossible.

"Move 'em, sir," came the answer, while the rifleman suppressed a grin of amusement. Jack was a favourite with them all, but he sometimes excited their ridicule. He was different from the steady and yet dashing Tom.

"Move 'em, sir, or interview one of these blackguards conducting the caravan. Look at the beggar nearest; stares at us as if we hadn't a right on the road, when we all know we're here to fight the Spaniards' own battles. Precious fine help they give us too! The only time they're out of the way is when fightin's wanted. Hi, you, you son of a gun, move along with you!"

The individual in question, a beetle-browed young fellow, whose head was closely swathed in a brilliantly-red handkerchief, and who dangled his sombrero from one hand, squatted on the shaft of the nearest waiting cart, puffing a cigarette and staring with insolent eyes at the commander of the irregulars.

"Cheek!" exclaimed Jack. "The beggar looks at us as if we were trespassers. Haul him up, Andrews; we'll give him trespassers."

Jack sought in the back of his mind for all the Spanish he knew and burst into an ungrammatical tirade when the muleteer was brought forward by Andrews.
