Introduction
Theย Cymmer Colliery explosionย occurred in the early morning of 15 July 1856 at the Old Pit mine of theย Cymmerย Collieryย nearย Porthย (lowerย Rhondda Valley),ย Wales, operated byย George Insoleย & Son. The underground gas explosion resulted in a “sacrifice of human life to an extent unparalleled in the history of coal mining of this country”[1]:โ141โย in which 114 men and boys were killed. Thirty-five widows, ninety-two children, and other dependent relatives were left with no immediate means of support.
The immediate cause of the explosion was defectiveย mine ventilationย and the use of naked flames underground. Factors contributing to the explosion included the rapid development of the mine to meet increased demand for coal, poor mine safety practices allowed by management despite official warnings, and deteriorating working relationships between miners and management.
After the explosion, mine ownerย James Harvey Insoleย and his officials were accused of “neglecting the commonest precautions for the safety of the men and the safe working of the colliery”.[2]:โ2โย At theย coroner’sย inquestย into the deaths, Insole deflected responsibility onto his mine manager Jabez Thomas and the jury brought a charge ofย manslaughterย against Thomas and the four other mine officials. To the outrage of the local mining communities, the subsequent criminal proceedings resulted in the exoneration of the mine officials from any blame for the disaster.
The Cymmer Colliery disaster influenced the introduction of mine safety improvements including legislation for improved mine ventilation and the use ofย safety lamps,ย employment of children, and qualifications of mine officials. The tragedy highlighted the need for a workable compensation scheme for miners and their dependents to reduce their reliance on public charity after such disasters.
Background
George Insoleย and his sonย James Harvey Insoleย purchased theย Cymmerย Collieryย in 1844. In 1847 they sank the No. 1 Pit which, after 1853, became known as the Cymmer Old Pit. James Insole took control of the business on his father’s death in 1851.[3][4]
Between 1852 and 1855,ย HMย Inspector of Mines Herbert Francis Mackworth inspected the colliery twice and sent letters to Insole recommending safety improvements, in particular to the mine’sย underground ventilation systemย and the use ofย safety lampsย underground.[3][5]
Colliers (miners) relied on the colliery firemen’s daily reports of gas hazards before entering the mine. In 1854, mine manager Jabez Thomas summarily dismissed two experienced firemen and appointed two others from outside the colliery. The workmen complained to Insole they had no confidence in these replacements. The men’s refusal to work under the new firemen, and Insole’s insistence on exercising his “authority to dismiss or employ those whom I please, without consulting any body of men”,[3]:โ133โย led to a twenty-two week miners’ strike. Financial loss and threat of legal action eventually compelled the men to return to work under the new firemen.[a][3]
By the mid-1800s, theย Rhonddaย variety of coal was in high demand as aย coking coal.[6]:โ48โย Theย Crimean Warย created additional demand for coal, and in 1855 Insole intensified his mining operations at the Old Pit, doubling the number of colliers and increasing the mine area by over a third.[3]ย Welsh historian E. D. Lewis concluded that,
It was the success of [the Cymmer Old Pit mine] when developed with such inordinate speed and recklessness by [George Insole’s] son,ย James Harvey Insole, that led directly to the terrible mining disaster of 1856.[3]:โ123โ
Explosion

On Tuesday, 15 July 1856, 160 men and boys descended the Old Pit mine shaft to commence their 6:00ย a.m. shift. As they made their way to their workplaces underground, there was an explosion of gas near the mine entrance which trapped the colliers already deeper in the mine. It was three hours before rescuers could reach the site. They found that many of the colliers had congregated in groups to die together as they ran out of air. By that evening,
112 bodies had been recovered, another was brought up the next day, and a severely burnt collier died the following day.[3][7][8]ย In his report to theย Secretary of Stateย for the year 1856, Mines Inspector Mackworth described the disaster as “the most lamentable and destructive explosion which had ever occurred in any colliery either in this country or abroad”.[5]:โ118โ
Inquest
Theย coroner’sย inquestย into the deaths began on 16 July 1856 in Porth before the Northย Glamorganย coroner George Overton and a jury of eighteen. It was adjourned to allow the jurors to view the bodies and reconvened eleven days later inย Pontypridd. Twenty-nine witnesses were called. The evidence indicated that the explosion resulted from defective mine ventilation and the use of naked flames underground, (Note: both theย Davy lampย andย Geordie lampย safety lamps had been invented in 1815, and widely used in mines at the time) despite warnings having been sent to the mine owner by Mackworth.[2][5]ย He told the inquest that “the explosion arose from the persons in charge of the pit neglecting the commonest precautions for the safety of the men and the safe working of the colliery”.[2]:โ2โ
The inquest determined that, apart from the collier who died later of burns, all the deaths were the result of “suffocation, caused by the post-explosion effects ofย afterdampย orย methaneย poisoning”.[3]:โ138โ139โย Among the 114 victims, thirty-four were boys under the age of sixteen and another fifteen were under the age of twelve. Insole, the mine owner, walked free from the inquest after claiming he took “no part in management”[9]ย of the mine. The mine manager, Jabez Thomas, and the mine’s officials, Rowland Rowlands (overman), Morgan Rowlands (fireman), David Jones (fireman), and William Thomas (fireman), were charged withย manslaughterย for negligence causing the deaths of 114 men.[2][3][10]
Trial
At the Glamorgan Springย Assizesย held inย Swanseaย in March 1857, the judge, His Lordshipย Baron Watson, made his own position clear in his pre-trial address to theย grand jury. Noting that the mine manager did not go underground, and that “no direct case of omission” had been brought against the other mine officials, he indicated that they could not be guilty of manslaughter.[1]:โ142โย Nevertheless, the grand jury returned a “true bill” (indictment) against Jabez Thomas, Rowland Rowlands, and Morgan Rowlands, who were then tried on the charge of “having feloniously and wilfully killed and slain one William Thomas,[b]ย on the 15th July, 1856″.[11]ย At the trial, it was reported that the judge made clear he sided with the defendants and thought the matter should not have come to court.[12]
At the conclusion of the trial, the jury complied with the judge’s directions to acquit the defendants.[1]ย To the deep distress and anger of the local mining communities, the final result of the legal proceedings was that the mine owner and his officials were exonerated from all blame.[3]ย However, E. D. Lewis’ analysis of the disaster concluded that:
Possibly the legal processes of the time were insufficient to punish those who were culpable, but of the moral responsibility of owner and officials, even when judged against the background of their own time and place, there can be no question.[3]:โ153โ
Survivors

Among the small local communities no household was left untouched, almost all the working-age men and boys having perished. Thirty graves were opened at theย Cymmer Independent Chapelย graveyard and the bodies of forty-eight victims were interred on 17 July 1856 in the presence of huge crowds (estimated at 15,000 people). Smaller numbers of burials occurred in other local communities, with “11 atย Tonyrefail, nine atย Ffrwd Amos, eight at theย Dinasย Methodist Chapel, and the rest at Pontypridd,ย Treforest,ย Coed Cymmer,ย Llantrissant,ย Llanharry,ย Bedwas, Trelanos,ย Brynmenyn, Wauntrodau,ย Llanwonno”.[8][3][7]ย Thirty-five widows, ninety-two children, and other dependent relatives were left with no immediate means of support.[14]ย The court’s verdict meant theย Fatal Accidents Act 1846, which required compensation to be paid only when a mine manager or proprietor was held to have been at fault, did not apply.[3]
However gross may have been the neglect which caused the husband’s death, all interests are arrayed against the survivors. The colliers, the jury, the means of legal redress, are subject to the influence โฆ [of] the proprietor of the colliery. The cost of an administration, before an action can be commenced, and the difficulty of obtaining a solicitor who will undertake the odium and the risk, unite in forming an insuperable bar to the claim due to the widow and the fatherless, who, by the neglect or cupidity of others, have been plunged in one moment into the deepest affliction and most abject poverty.
Mines Inspector Mackworth’s report to theย Secretary of State, 1855[15]:โ118โ119
The dependents of the victims of the disaster had to rely on public charity and “the final humiliation” of seekingย poor relief.[3]:โ160โ[14]ย Insole contributed ยฃ500 (approximately equivalent to ยฃ49,700 in 2021) to theย Cymerย Widows’ and Orphans’ Fund, set up shortly after the disaster, and undertook to meet the cost of the thirty graves.[3][16]ย However, local coal owners also combined to deny work to those colliers who had given evidence against the mine officials at the inquest and trial.[3][5]Lamentsย were published and, marking the first anniversary of the disaster, a song was published under theย patronageย of Mrs Insole ofย Ely Courtย (Insole’s wife) in aid of the relief fund.[17][18][19]
Legacy
Described by Mines Inspector Thomas Evans as a “sacrifice of human life to an extent unparalleled in the history of coal mining of this country”,[1]:โ141โย the Cymmer Colliery disaster of 1856 influenced future coal-mining practices, locally and nationally. After another gas explosion at the colliery in December 1856,[20]ย the single-shaft Cymmer Old Pit and New Pit mines were linked to create a safer and better ventilated two-shaft arrangement. Although mechanical mine ventilators had been used in the Lower Rhondda from 1851, they were installed at the Cymmer Colliery in the mid-1870s. Also by the mid-1870s, the colliery management realised it was safer and cheaper to provide colliers with safety lamps. The Cymmer Old Pit was worked by the Insole company until the mine closed in 1939.[3][6]:โ149โ160โ
More broadly, influenced by the number of children killed in the disaster, theย Mines Regulation Act 1860ย prohibited employment of boys under twelve years of age, unless they could read and write and were attending school for at least three hours a day on two days a week.[3]ย Two-shaft mines were made compulsory by 1865. Mackworth’s safety recommendations, sent to Insole in 1854 and including “that a qualified mining engineer and a sufficient number of competent subordinate officers and deputies should take complete charge of the machinery, ventilation, ways and works and watch over and provide for the safety of the workmen during the hours of labour”,[3]:โ159โย were passed in theย Mines Act 1872. Following the Cymmer Colliery explosion, steps were taken to reduce the reliance on public charity in the case of fatal disasters by introducing comprehensive compensation schemes, but the first successful scheme did not emerge until 1881.[3][5][21][22]
