They proceeded to assert unfounded claims to civil jurisdiction over Punta Arenas, a position on the opposite side of the river San Juan, which was in possession, under a title wholly independent of them, of citizens of the United States interested in the Nicaragua Transit Company, and which was indispensably necessary to the prosperous operation of that route across the Isthmus. The company resisted their groundless claims, whereupon they proceeded to destroy some of its buildings and attempted violently to dispossess it. At a later period they organized a strong force for the purpose of demolishing the establishment at Punta Arenas, but this mischievous design was defeated by the interposition of one of our ships of war at that time in the harbor of San Juan. Subsequently to this, in May last, a body of men from Greytown crossed over to Punta Arenas, arrogating authority to arrest on the charge of murder a captain of one of the steamboats of the Transit Company. Being well aware that the claim to exercise jurisdiction there would be resisted then, as it had been on previous occasions, they went prepared to assert it by force of arms. Our minister to Central America happened to be present on that occasion. Believing that the captain of the steamboat was innocent (for he witnessed the transaction on which the charge was founder), and believing also that the intruding party, having no jurisdiction over the place where they proposed to make the arrest, would encounter desperate resistance if they persisted in their purpose, he interposed, effectually, to prevent violence and bloodshed. The American minister afterwards visited Greytown, and whilst he was there a mob, including certain of the so-called public functionaries of the place, surrounded the house in which he was, avowing that they had come to arrest him by order of some person exercising the chief authority. While parleying with them he was wounded by a missile from the crowd. A boat dispatched from the American steamer Northern Light to release him from the perilous situation in which he was understood to be was fired into by the town guard and compelled to return. These incidents, together with the known character of the population of Greytown and their excited state, induced just apprehensions that the lives and property of our citizens at Punta Arenas would be in imminent danger after the departure of the steamer, with her passengers, for New York, unless a guard was left for their protection. For this purpose, and in order to insure the safety of passengers and property passing over the route, a temporary force was organized, at considerable expense to the United States, for which provision was made at the last session of Congress.
