Built in 1843, it took passengers from Cork in the south of Ireland to the ports of Liverpool, the first leg for emigrants wishing to start a new life in the United States.

An iron built steamer, Nimrod had a gross register tonnage of 582 tons and was rigged with sails in the event of engine problems.

Carrying passengers and some general goods to the sum of £7,000 it experienced a problem with its engines roughly 15 miles from Smalls Lighthouse.

Nimrod was observed in the morning of 28 February, with sails now tattered, off the St David's Head, being driven to the cliffs.

[4] The wreck of Nimrod is located in three sections in the Porth Llong Cove off St David's Head.
