When it was proposed to get a city charter for Cleveland, negotiations were entered into between the leading men on both sides of the river with the purpose of either consolidating the two villages into one city, or at least acting in harmony. The parties could agree neither on terms of consolidation nor on boundaries. The negotiations were broken off, and each side started its deputation to Columbus to procure a city charter, with the result we have already noticed. Ohio City was ambitions to have a harbor of its own, entirely independent of Cleveland and to the advantages of which that city could lay no claim. The old river bed was to be deepened and the channel to the lake at the west end re-opened. As a preliminary to this ignoring of the Cleveland harbor entrance of the Cuyahoga, a canal was cut through the marsh, from opposite the entrance to the Ohio canal to the old river bed, which was thus to be made the terminus of the Ohio canal. In 1837, city rivalry ran so high that it resulted in the "battle of the bridge." Both sides claimed jurisdiction over the Columbus street bridge built by Mr. Clark and donated for public use. Armed men turned out on either side to take possession of the disputed structure. A field piece was posted on the low ground on the Cleveland side, to rake the bridge. Guns, pistols, crowbars, clubs and stones were freely used on both sides. Men were wounded of both parties, three of them seriously. The draw was cut away, the middle pier and the western abutment partially blown down, and the field piece spiked by the west siders. But the sheriff and the city marshal of Cleveland appeared on the scene, gained possession of the dilapidated bridge, which had been given to the city of Cleveland, and lodged some of the rioters in thee county jail. This removed the bridge question from the camp and battle-field to the more peaceful locality of the courts. In 1840, the population had increased to 6071, so that, notwithstanding that the city had been suffering from depression, there was an influx of a thousand persons in the last five years. In 1841, the Pennsylvania and Ohio Canal was completed, Connecting the Ohio Canal at Akron with the Ohio river at Beaver, Pennsylvania, and thus forming a water communication with Pittsburgh. The United States Marine Hospital, pleasantly situated on the banks of the lake, was commenced in 1844 and not completed until 1852. It is surrounded by eight acres of ground, and is designed to accommodate one hundred and forty patients. In 1845, the city voted to loan its credit for $200,000 towards the construction of a railroad from Cleveland to Columbus and Cincinnati, and subsequently the credit of the city was pledged for the loan of $100,000 towards the completion of the Cleveland and Erie or Lake Shore line.
