The night of the 11th, Capt. Hankins, with two native boys, was sent to San Juan del Sur to get the correspondence brought from Panama by the Orizaba. On the night of the 14th he returned to Rivas, and added to the commissary stores by riding in on horseback. The letters from the San Juan river gave the news of the arrival of Capers and Marcellus French with their respective commands; while those from New-York too well confirmed the surmises of Walker’s friends in California, for they gave notice of the intention of Garrison and Morgan to cease running their steamers. It is unnecessary to go into the reasons which induced these men to the course they took; for it would involve an investigation into transactions uninteresting if not positively distasteful. Suffice it to say that their conduct was the result of weakness and timidity. As to their treachery, Walker had expected them to remain faithful to the Americans in Nicaragua only as long as their interests required fidelity; he expected them, however, to show more commercial nerve and sagacity than they displayed. Their course evinced as much folly as timidity, and jeoparded their reputation of skilful merchants fully as much as it damaged their character for honesty and integrity. From the 14th to the 23d, a number of skirmishes took place between parties of the enemy and small bodies of the Americans who went out to gather plantains; but none of these was serious or deserving of special notice. One of these skirmishes occurred on the morning of the 23d; and in the afternoon of the same day, a flag of truce brought letters to Walker announcing that Lieut. Huston, of the St. Mary’s, was at the headquarters of the Allies, and was ready, under the United States flag, to conduct the women and children in Rivas to San Juan del Sur. A letter from Mora to Walker proposed to send two of his aides with Lieut. Huston to a convenient-point between the camps, where the United States officer might be met by two of Walker’s aids, and be thus conducted into Rivas. In accordance with this proposition, Hooff and Brady accompanied the native boy who bore the letters from Mora to a point about half way between the camps, and there halted, waiting the approach of Lieut. Huston. While these two officers waited, a couple of deserters approached and attempted to address them; but Hooff, drawing his pistol, warned the fellows off under peril of their lives. Then, indignant at the Allies for permitting such an insult as the approach of deserters to officers bearing a flag of truce, Hooff and Brady returned to Rivas without waiting longer the arrival of Lieut. Huston. Soon after, however, Lieut. Huston entered the town, accompanied by a corporal of marines.
