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. Within minutes, 40 people including children perished in the flooded workings, leaving a devastating mark on the local community.
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.
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.
14th February 1844: Day of the Disaster
Reconstructed timeline of events from local newspaper reports and inquest records.
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.
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.
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."
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.
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.

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.
