Four hours had passed since then, and at length Duckworth was forced to recognise that not alone would he have only his pains for his labour, but that he was hopelessly lost amongst the intricacies of the Sierra de Avila. The valley that had seemed so full of feature at first, was for him featureless. Each subsidiary glen seemed exactly like the other; every spur looked the twin of the next. To add to the difficulties of the situation the mists had come down to within a hundred feet of the bottoms. Moreover, he had disobeyed orders; and he realised that when he returned—_if_ he returned—to camp, his reception by Sir Edward Pakenham, however reasonable his excuses, would be the reverse of sympathetic. He had excuses, or rather explanations, which had appeared quite satisfactory an hour or so ago. It was true that a general order had been issued that scouts were not to venture far out of touch with the outposts; but in the circumstances, the order had seemed inapplicable—a few hours ago. The reason for the order was that recently no fewer than four officers employed on reconnaissance duty among the hills had failed to return to headquarters at Fuente Aguenaldo. The French knew nothing of them, and the French were honourable adversaries. On the other hand, the inhabitants of the Sierra were Spanish irregulars—our allies, guerrillas who varied the intervals between action and retreat by remunerative military exploits, flavoured under favourable conditions by torture. It was not inconceivable that these gentlemen might have failed to differentiate between the French and English nationalities in the case of the absentees. Explanation I.—Duckworth had seen the King’s uniform on a stray figure—presumably that of one of the missing officers. It was therefore his duty to ride in search of him. Explanation II.—The hills in that neighbourhood were innocent of guerrilla—for a season, at least. Early in the day, Duckworth had watched a force of French rounding up a large body of his irregular allies at the point of the bayonet, in a businesslike manner that evoked his enthusiastic admiration. Result!—Disobedience to orders and nothing whatever to show for it. If his thoughts were gloomy, his surroundings were depressing. Every stream, every runnel, every trickle, was frothing with dirty grey soapsud-coloured water; the clean white limestone cliffs had taken a dull, grey, lifeless, unwashed hue; the dripping dank leaves seemed to be doing their best to turn grey, and over all the mist stretched its grey, unwholesome canopy. For some time he had followed the river, the general direction of which would, he knew, take him towards the British lines; but all at once the water, after the exasperating habit of mountain streams in limestone countries, slipped underground, leaving a trackless chaos of stones and boulders. Disgustedly the Major turned his charger’s head, trusting to luck to find a way out somehow to somewhere.
