Under the influence of these measures of the government, the number of Americans had been rapidly increasing since the first of November, 1855. Mr. Fabens, who was in Granada at the time Walker entered the city, went, soon after the treaty was signed, to San Juan del Norte, and induced many of the Americans with Kinney to join the army of Nicaragua. On the 7th of November Capt. R. W. Armstrong, with a company from San Francisco, arrived at Granada, and thus the American force was swelled to upward of two hundred men. After this, until the arrival of Capt. Anderson on the 17th of December, the increase was by small numbers at a time, and in the meanwhile the cholera had appeared at Granada. The disease seemed to select those officers who were most capable and useful, and there were suspicions that the people of the town, mostly Legitimists, were not entirely ignorant of the cause which produced the deaths of leading Americans. Among the first victims of the disease were Capt. Davidson and Col. Gilman; and the death of the latter was a severe loss. Then Capt. Armstrong and Major Jesse Hambleton passed away. The deaths finally became daily, and the frequent sound of the dead march, as the funeral escorts passed through the streets, began to exercise a depressing effect on the troops. The surgical staff was inexperienced, and the services of some volunteers were valuable. Dr. James Nott was the most efficient of these, and many a Nicaraguan, who owed his life to this surgeon’s kind and skilful attention, regretted his departure and mourned his death, which occurred on the passage from San Juan del Norte to New-Orleans. It was only after the arrival of Dr. Israel Moses, early in February, 1856, that the surgical staff was well organized and its duties well performed. He gave such order and system to this department of the army that the good effects of his administration were felt long after he ceased to act as surgeon-general. Indeed, it is safe to say that after the appointment of Dr. Moses few military hospitals were better administered than the hospitals at Granada and Rivas. In spite, however, of the fearful ravages of disease, the number of Americans continued to increase, most of the immigrants coming from California until the month of March, 1856. A few, during January and February, had come from New-York and New-Orleans, but it was not until Goicouria arrived, early in March, that any numbers were received from the Atlantic side. So successful had been the policy of the Rivas administration for the introduction of the new element, that on the 1st of March, 1856, there were upward of twelve hundred Americans, soldiers and citizens, in the Republic, capable of bearing arms. It remains, now, for us to see what effect this domestic policy of the Provisional Government had produced in its foreign relations.
