Maritime co-operation of a similar kind had been carried into effect on the northern coast of Spain. About midsummer Commodore Mends of the Arethusa frigate consulted with the Junta of Asturias, who engaged to put what they called the armies of that province, and of the Montañas de Santander, in motion, if he would take Porlier and 500 men on board his squadron and beat up the enemy’s sea-quarters. This it was deemed would draw the French troops towards the ports in their possession, calling them from the frontiers of Galicia, which they were then threatening, give the mountaineers opportunity to act with advantage, and favour the Guerrillas in Castille, whom the French were endeavouring to hunt down. The Commodore had no instructions for an expedition of this kind, but he saw that it offered a reasonable prospect of advantage; for if the Junta should fail in their part of the undertaking, or be disappointed in their hopes, he might nevertheless destroy the enemy’s sea-defences, and cut off the supplies which they received coast-ways. Accordingly Porlier with his men embarked, and the squadron sailed from Ribadeo. The wind serving for Santona, they landed on the beach to the westward of that place. The garrison there, some 120 in number, retired with the loss of about thirty men; and the French commander at S. Sebastian feared that it was their intention to establish themselves there, in a post which might easily have been rendered defensible, and would afford good anchorage during the prevalence of the westerly gales upon that coast: the utmost efforts therefore were made to prevent this; and on the second day after the landing, from seven to eight hundred French attacked them on the isthmus. This body was repulsed with considerable loss; but finding that the enemy were collecting in greater force, the Commodore re-embarked his men on the following day, having destroyed the fortifications. Pursuing his object, he demolished all the batteries upon the coast between S. Sebastian’s and Santander (those at Castro alone excepted), carried off or threw into the sea above a hundred pieces of heavy cannon, and laid that whole extent of coast bare of defence, without the loss of a single man; and having made about two hundred prisoners and taken on board three hundred volunteers, all for whom room could be found, the squadron returned to Coruña. ♦EXPEDITION TO SANTONA UNDER RENOVALES.♦
