19 April 1851  Gloucester Journal A most lamentable accident was discovered to have taken place on Saturday week, at the Brockhole Ditches coal pit, belonging to the Parkend Coal Company.  The men, on decending the  pit in the morning, found the whole underground works filled with smoke.  Attempts made to save the horses but without effect.  Four valuable ones were found dead, and two others, which it was impossible to get at have undoubtably met the same fate.  All efforts to trace the source of the fire proved fruitless and the only option was to seal the mouth of the pit.  Works now stopped, upwards of 100 men and boys being thrown out of employment.

26 April 1851 Gloucester Journal  Damage is much less than first thought.  No permenant damage has been done to the colliery and there will be but trifling damage beyond the loss of six valuable horses and the burning of a considerable quantity of timber in the horse road.  Accident a result of gross carelessness on the part of some colliers, all of whom are the sufferers by the temporary stoppage of the pit.
