For two years subsequently to his return from Walcheren, Sir Howard led a quiet and useful life as head of the Military College. In 1811, however, a fresh opportunity was found for employing him abroad. The Government of that day put a far higher value on the services of the Spanish guerillas than they deserved, and were incredulous of Lord Wellington’s assurances, that on the regular armies of Spain no dependence could be placed. It seemed to Lord Liverpool and his colleagues that the Spaniards, if properly armed and supplied, were capable by their own valour of driving the French beyond the Pyrenees; and they made choice of Sir Howard Douglas to go among them, because they believed that he possessed talents and energy enough to awaken them to a sense of their duty. He received instructions, therefore, towards the end of July, to proceed without delay to Lord Wellington’s headquarters, and to arrange with him all details respecting his future proceedings. Perhaps there is no interval in the long and useful career of Sir Howard Douglas which afforded him more frequent opportunities of doing good service to his country than that which, extending over little more than a year, was spent by him in Spain; but the tale is one which will not bear condensation. After conferring with Lord Wellington on the Portuguese frontier, Sir Howard rode across the country to Oporto, and thence took a passage by sea to Corunna. He entered there into relations with Spanish juntas, Spanish generals, and the chiefs of guerilla bands, and found them all, with the exception of one or two individuals belonging to the latter class, even more impracticable than he had been led to expect. He gave them first arms, money, clothing, and had the mortification to learn that the best battalions and batteries, as soon as they became fit for war, were shipped off for South America. He turned next to the irregulars, and succeeded in getting a levy _en masse_ set on foot, which very much perplexed, and gave constant occupation to, the French troops scattered over that and the adjoining provinces. But the circumstance which more than any other affected his own fortunes, was a combined attack on the fortified convent of St Cintio Rey by Sir Home Popham’s squadron from the sea, and the guerilla band of Don Gaspar on shore. It was while watching the effect of the Venerable’s fire that Sir Howard became struck with the ignorance of the first principles of gunnery which manifested itself both among officers and men, and that he conceived the idea of applying, should leisure ever be afforded him, a proper remedy to the evil. From that idea emanated his first great treatise, to which the British navy owes so much, and of which the rulers of the British navy, the Lords of the Admiralty, did not condescend, for many months after it had been submitted to them, even to acknowledge the receipt.
