Thus in the bold but fruitless charge he made on San Jacinto perished Byron Cole, whose energy and perseverance had done so much toward securing the presence of the Americans in Nicaragua. It was the first opportunity he had for being under fire; and he had scarcely seen the flash of an enemy’s musket before he met his fate. For months preceding the arrival of the Americans at Realejo, he had travelled and toiled in their behalf; and the only reward of all his labor and anxiety was death on the first field where he met the foe of the principles he had aided to advance. Nor was Cole the only loss of note on that fatal day. Marshall died of his wounds after reaching Tipitapa; and among the missing was Charles Callahan, who had been appointed collector of customs at Granada. The latter was correspondent of the New-Orleans Picayune newspaper, and his genial nature secured for him a large circle of friends who regretted his untimely loss. The thirst for action led him to exchange his business in Granada for the excitement of the attack on San Jacinto; and he never returned to fill the duties he had so well begun a few weeks previously. The retreat of the volunteers from San Jacinto was irregular and disorderly; and on such a command as that of McDonald at Tipitapa the arrival of the defeated party had an alarming effect. So great was the panic that the bridge across the river was torn up to prevent the expected enemy from using it. But no enemy appeared and the alarm gradually subsided. The news, however, of the defence at San Jacinto encouraged the Allies greatly; and soon after the news of the affair reached Leon, Belloso, urged on by some of the more resolute of his officers, determined to advance toward Granada. A few days after the affair at San Jacinto, about two hundred men arrived at Granada from New-York for the Nicaraguan service. They were soon organized into companies; but they showed from the beginning how worthless they were for military duty. A very large proportion of them were Europeans of the poorest class, mostly Germans who cared more for the contents of their haversacks than of their cartridge-boxes. With the exception of Captain Russell and Lieutenants Nagle and Northedge, the officers were as trifling as the men; and these New-York volunteers, as they called themselves, had not been in the country ten days before they began to desert in numbers. The promise of free quarters and rations seemed to have carried the most of them to Nicaragua; and the idea of performing duty could scarcely have entered their minds when they left the United States. Of course such trash as these men proved to be were far worse than no men at all; for their vices and corruptions tainted the good materials near them.
