Early in February the monotony of the siege was broken by the arrival at San Juan del Sur of the American man-of-war _St. Mary's_, Commander C. H. Davis. Promptly in her wake came the British steamer _Esk_, Captain Sir Robert McClure. The two formidable ships lay not many cable lengths apart in the harbour. The day after his arrival Sir Robert sent a boat's crew aboard a small schooner lying near the shore to ask the meaning of the ensign which she was flying at the masthead. It was a handsome flag, composed of three horizontal stripes, blue, white, and blue; in the middle stripe, which was twice the width of either of the outer ones, was a five-pointed red star. The ensign was that of the new republic of Nicaragua, and the vessel, as her commander, Fayssoux, politely replied, was the Nicaraguan schooner-of-war _Granada_. Sir Robert then ordered him to come on board the _Esk_, and bring his commission with him; to which the plucky Louisianian, with the blood of revolutionary ancestors boiling at the impertinence, replied that he would do nothing of the kind; and when the English captain threatened a broadside, the Nicaraguan commander beat to quarters--he had a score of men--loaded his two six-pound carronades, and awaited destruction as calmly as if he had the deck of a seventy-four under his feet. But Sir Robert, either fearing to exceed his authority, or labouring under the delusion that the _St. Mary's_ captain might not relish the idea of seeing his fellow-countrymen annihilated before his eyes, softened the demand into a request for a friendly visit, which Captain Fayssoux thereupon paid him. A nobler motive may have actuated Sir Robert, for he was a sailor, and had traditions of his country's honour, which it were worth an American officer's commission to entertain. The latter has never forgotten the awful example handed down from the early days of Commodore Porter, who was court-martialed and forced out of the service because he exacted an apology from some Spanish vagabonds who had imprisoned an American officer visiting Porto Rico under a flag of truce.
