The Landshipping Disaster

Garden Pit Colliery Inundation • 14 February 1844

Historical Mining Catastrophe

The Garden Pit Disaster of 1844

On Valentine's Day in 1844 at 4:00 PM, the waters of the River Cleddau burst through the roof of the Garden Pit colliery in Landshipping, Pembrokeshire.40 people including children perished in the flooded workings, leaving a devastating mark on the local community.

The reason for my interest in researching this is John Cole aged 19 the brother of my 5th great grandmother died in the disaster. This eventually lead to my surviving ancestors to move to Mountain Ash where new coal mines were being opened.

The Incident at a Glance

The Garden Pit colliery worked seam beds extending over a quarter-mile underneath the tidal River Cleddau. After weeks of paused work, 58 workers returned to work a section that had been left unworked for three years due to safety concerns.

Early in the shift, workers reported salt water dripping onto their heads. Despite warnings, work continued. At around 3:30–4:00 PM, a catastrophic breakthrough occurred. The main shaft flooded to a depth of 90 feet (15 fathoms) in roughly one minute.

Economic & Social Aftermath

The inundation forced the permanent closure of the Garden Pit colliery. The loss of 40 lives dealt a devastating financial and social blow to the small parish of Landshipping and surrounding villages.

Over subsequent decades, as neighboring pits gradually closed by 1867, some local mining families migrated eastward to the expanding coalfields of Glamorganshire and the South Wales Valleys in search of work.

Chronology of Events

14th February 1844: Day of the Disaster

Reconstructed timeline of events from newspaper reports, Old books and a few other sources listed below.

Morning • Feb 14, 1844

Resumption of Work & Early Warnings

58 workers enter the Garden Pit to renew their labour contracts after a multi-week pause. Workers are assigned to a section extending 1/4 mile under the tidal River Cleddau—an area unworked for 3 years due to safety risks.

💡 Warning ignored: Colliers reported feeling salt water dropping onto their heads early in the day. Some turned back, but were assured everything was safe and told to carry on.
3:30 PM – 4:00 PM

Riverbed Inundation & Panic

A massive blast of displaced air rushes through the pit shaft. River mud and water break through the overhead roof, turning the shaft into a violent whirlpool.

Around 4:00 PM

Desperate Escape via Buckets

Two empty winding tubs/buckets are at the shaft base. 14 men and boys scramble in as water rises rapidly. One man slipping into the torrent shouts: "Oh, Lord! have mercy on my soul."

⏱️ Quick Disaster: Very quickly, water floods the shaft to a depth of 90 feet (15 fathoms). 33 colliers trapped deep inside, 7 overtaken near the shaft.
February 15, 1844

Secondary Air Pressure Explosion

The day after the flooding, compressed trapped air violently erupts from the shaft, hurling heavy structural timber high into the air. No bodies could be recovered.

March 1844

Relief Sermons & Financial Ruin

Sermons preached at St. Alan's (£45 16s raised) and Boulston Church for widows and orphans. Mine owner Sir John Owen incurs heavy debt and is forced to sell property to avoid bankruptcy.

🥀 The colliery was permanently abandoned. Landshipping never economically recovered, sparking gradual emigration across South Wales.

A weekly newspaper that focused on local news and some national news.

Three of the boys who were nearest to the mouth of the pit, were alarmed by hearing a violent rushing of water in the interior of the works; they instantly ran to the pit’s- mouth, and were only just in time to save their lives, by climbing up the sides of the pit, before the water filled the level—had they been a moment later, the water would have overwhelmed them, as it did all their unfortunate companions who were in the interior. It was immediately afterwards found that a portion of the ground underneath the mud on the side of the river, a little above low water mark, and directly over the level, had given way, and the tide, which was then flowing, was observed to rush with great force towards the fissure, so as to drown the works, and render the escape of the hapless colliers utterly hopeless. Tidings of the sad calamity were quickly conveyed to the village where the workmen had resided, and as soon as the nature and extent of it were ascertained, a scene of the most heart-rending kind was exhibited among the surviving wives, mothers, and other relatives of the unfortunate workmen, which is far easier to imagine than to describe. Immediately after the boys had come above ground, the landing tub was lowered to assist any one who might be at the bottom of the pit, but when it was pulled up it was found to contain nothing but water. Some short time afterwards the steward of the works went down but he could not discover anything but pieces of timber floating on the surface.

[The late Fatal Accident at Landshipping Colliery—Forty Lives Lost. MILFORD, Feb. 21st.—From particulars ascertained, in addition to those given in our last, it seems that about half-past three or four o’clock in the afternoon of Wednesday, when there were 58 persons at work below in a large pit called the garden pit, the works of which extend to a considerable distance under the river, the parties at the mouth of the pit became aware that some accident had occurred by a powerful current of air making up the pit, so strong, to use the language of one of the bystanders, as to bear up a hand held unresistingly over it, and at the same instant, the water at a little distance from the shore became much agitated, eddies being visible to a considerable extent: shortly afterwards several persons rushed out into the shaft of the pit shrieking wildly for help; the man at the whim immediately put the horses to the gallop, and succeeded in rescuing four men and fourteen boys, when the water rushed with such force towards the mouth of the pit, as to render further exertions unavailing. One of the survivors states that he and another man were alarmed by a rushing wind stronger than any storm he had ever heard, which completely carried them off their legs, and at the same time extinguished the lights; thinking it was occasioned by the explosion of fire-damp, he called to his companions to stand still, but having discovered his mistake he at once saw that their only chance of escape was by flying to the mouth of the pit. In their way thither his companion appears to have lost his footing, as he heard him exclaim, “Oh, Lord! have mercy on my soul.” He himself was overtaken by the water, which almost prevented his progress, dashing him several times against the sides of the pit. When he got into the light, he rushed past another man, sprang into the bucket, and was taken up; the water following him so closely, that the next and last man was only saved by climbing up the side of the pit till the descending bucket reached him. The water appears to have broken in at a comparatively short distance from the shore, and pouring down in a body, at once cut off all chance of escape from 33 persons who were at work farther in; the remaining seven, who were nearer out, must have been overtaken in their attempt to escape. A violent explosion took place the following day, occasioned by the pressure of the water on the air confined in the recesses of the pit; large pieces of timber being thrown up to a considerable height. The following are a few of the distressing bereavements occasioned by this melancholy occurrence.—One man and three of his sons were drowned, leaving a widow and five children; another man and his son, also leaving a widow and five children. Five other men have left widows and eighteen children; the remainder were unmarried men and boys.]

During this period in Wales Christianity was a big part of people's lives and the culture. People's faith played a big part in dealing with the aftermath. Some local churches did special services and sermons for the victims. During these special services the collection money was given to the bereaved families. This would have been greatly needed and appreciated as many families lost the person or persons they were dependent on financially.

"A sermon was preached at St. Mary's on the 3rd instant by the rector, in behalf of the widows and orphans of the unfortunate colliers drowned in the coal works at Landshipping, and contributions have since been collected throughout the town to the amount of £45 16s [16s shillings]. This speaks well for the liberal and charitable spirit of our inhabitants. "

"The Garden pit colliery, very close to the quay, was quite famous locally; but in 1844 it hit the national headlines. Water from the river broke into the workings, and more than forty men and boys were drowned. The mine was closed and the community never recovered. Many families emigrated, and by 1867 all the other collieries in the area had also closed. “

"In a quiet little cottage home at Landshipping, live three elderly sisters, Elizabeth, Martha, and Mary Butler, of whom Elizabeth is one of the very few women now living who once worked in a colliery. She was employed at the ‘Garden Pit,’ at Landshipping, for several years at the noble sum of 4d. a day, the man's wages at the time being 1s. a day. They lost two of their brothers in the flooding of the Garden Pit, a catastrophe which occurred a few days after the passing of Lord Davey's Act rescued Elizabeth Butler from working in the colliery. “
