Distinct from John Craggs 'Mersey Iron Foundry' in Tithebarn Street 'The Mersey Forge' was founded by Mr. Ralph Clay in in 1810.  In 1855 William Clay was manager. Robert Griffiths records that in 1864 the company officially became 'The Mersey Steel and Iron Co. Ltd'. Prior to this name change, the forge occupied land on either side of Sefton Street, but after incorporation it moved its position to allow for the construction of the Garston Railway line, which cut through the premises. The forge then also benefited from its own railway access, by means of a siding.
The Forge now straddled either side of the south end of Grafton Street, separated by Sefton Street and Horsfall Street, it was spread over three sites in all. The different parts were connected by tunnels.

At its peak over 1,500 men were employed there, mostly
on work for the Admiralty and various foreign governments.  The high wages which were paid brought a new prosperity to the district. The Mersey Forge had a history of government munitions contracts, manufacturing mostly battleship parts and large guns. In 1845 they constructed an un-named 'huge gun' , 13 feet long for the American frigate 'Princetown', (not to be confused with the Peacemaker gun which exploded on the American frigate  'Princeton' in 1844). Parts were made for the H.M.S. Penelope, an ironclad battleship launched on 18th June 1868. (this became a prison hulk in 1897 before being sold for scrap  in 1912). Also for H.M.S. Achilles an Ironclad frigate launched in 1863.  Navy vessels associated with the forge are Agincourt  (later renamed Boscawen III, Ganges II and broken up in 1927), Achilles, Minotaur (later renamed Boscawen II, then Ganges, then broken up in 1922) and Penelope.  All of these were present at Portland Harbour on 10th August 1872 when Prince Albert laid the final stone of the breakwater there. Minotaur was part of the Channel Fleet (there was a pub of that name nearby) and along with Northumberland and Hercules, under the command of Rear Admiral Hornby, this fleet visited the Mersey on 22nd June of this same year.

In 1855 The Northern Daily Times contained a detailed report which is available on the excellent Old Mersey Times site. It is notable that Mr William Clay was the manager at that time and it is difficult to resist suggesting a link to the founder Ralph Clay. Mr W.J. Horsfall was one of the proprietors at this time. He and his family are connected both with Horsfall Street and with various churches in toxteth.

In
1856, when owned by Messrs Walsall, the forge produced 'The Monster Horsfall Gun' weighing an incredible 21 tons and 17 cwt.  This 13 inch, smoothbore gun was tested on the north shore, near Formby. Apparently its transportation there was along streets decked with bunting and crowded by enthusiastic onlookers. A newspaper of the time records that  "for presentation to the government  it was proved that a ball weighing 300 pounds might be shot with effect 5 miles"  This test was on May 21st 1856 , the Crimean War Society states that the peace treaty was signed on 1st April 1856!   It is an irony and perhaps a blessing that this gun never reached the Crimean War for which it was intended. 'The Scientific American', April 26th, 1862 mentions this exact gun.

I was delighted to discover that The London Illustrated News for September 6th of 1856 contained an illustration entitled "Horsfalls Monster Wrought-Iron Gun". John Weedy who runs the Illustrated London News site at  www.iln.org.uk  went to a lot of trouble to photograph this woodcut for use here, (above, left) and I am very grateful to him both for this and for the copy of the attached text, (right) which I did not know about..
 
 In 1862 another gun ' The Prince Alfred' was exhibited at South Kensington. The size and weight of these guns was so great as to influence the design of the ships which they armed. A fascinating site  describes and illustrates the history of guns of the same weight, cast in the same years, but used in the American Civil War.  Finds from this period at the Woolwich Arsenal in London are preserved and treasured, a 42 lb gun is on exhibit there, what a shame that we do not know what was the eventual fate of the 42,000 lb Horsfall Gun.

One, much reported, feature of the forge was a massive steam hammer, a hammer so large that its sound could be heard on the other side of the River Mersey. The piston and hammer together weighed 15 tons. The hammer, however, was closed down as a result of complaints and an eventual injunction brought both by local householders and mill owners.

The Mersey Forge started to decline about 1878.  Government contracts dried up and it seems to have closed gradually, with various items of machinery and plant being removed little by little. The final shipment of scrap iron was sent from there in 1898.

B
y 1908 the "deserted and ruined remains" of the Mersey Forge "presented a melancholy spectre of their former greatness".  Part of the site was later used for coopering and part of the North Yard was developed for housing. Some of this housing remains today but it is missing from the 1905 map of the area, thus dating its development with a degree of accuracy. The photograph (left) taken from the chimney of the nearby Lavrock Bank Incinerator, shows the former yards of the Mersey Forge after clearance. 

A  part of the south yard has now been cleared and looks ready to be developed as does the adjacent Caryl Street gasworks.
