G. S. Hillard, Life and Campaigns of George B. McClellan, Major-General , U. S. Army

Captain McClellan drew up two reports, one on the harbor and its defences, and one forming a general memoir on the island. They have never been printed, and are probably still on file in the archives of the War Department. Our Government entered into negotiations with the Dominican Republic for the cession of the bay and peninsula; but they were not crowned with success. It may be surmised that the influence of France and England, exerted through their representatives, may have prevented it.

After returning home from the West Indies, Captain McClellan was stationed at Washington, employed on duties connected with the Pacific Railroad surveys. In the autumn of 1854, he drew up a very elaborate memoir on various practical points relating to the construction and management of railways, which was published in the same volume with the reports of his explorations. The Secretary of War remarks upon it as follows:--“Captain McClellan, of the Corps of Engineers, after the completion of his field-operations, was directed to visit various railroads, and to collect information of facts established in the construction and working of existing roads, to serve as data in determining the practicability of constructing and working roads over the several routes explored. The results of his inquiries will be found in a very valuable memoir, herewith submitted.”
