The four early steamers ( Britannia, Acadia, Caledonia and Columbia ) were soon reinforced by two others when it was found that increasing traffic demanded extension of the mail service. The Hibernia and Cambria were ships of increased dimensions, power and more extensive passenger and cargo capacity than their predecessors. When they were originally commissioned they were barque-rigged, but like the rest of the paddle-wheel steamers so built the third mast was soon done away with.
The Cambria was launched on 1 August 1844 and made its maiden voyage from Liverpool to Halifax and Boston on 4 January 1845. From 1848 onwards it began to alternate its destination between New York and Boston. In March 1854 it was requisitioned by the government to serve as a troop transport in the Crimean War. After this it resumed the Liverpool to Boston service.
In January 1860 it was sold to Garibaldi to be used as a troopship and in November that year it was taken over by the Sardinian Navy. It served the Italian Navy from March 1861 until it was scrapped in 1875.
