"On the occasion of the explosion which took place in the Factory on 18th January, he was engaged on the work of purification of nitroglycerine inside N.2 Washing House. This building, which is only 100 yards from the scene of the explosion, suffered considerable damage; half the roof was torn off, two-thirds of the walls collapsed, and the hot water and air services were interrupted. This gave rise to a condition of acute danger due to the possibility of the nitroglycerine freezing with the attendant risk of detonation. Despite this damage and being aware of the serious situation which had developed,
Sylvester continued at his post for at least two hours, until services were restored and the whole charge had been processed and brought to a state of stability. Had he left his post with the charge of over one ton of nitroglycerine standing in its unstable condition, another explosion might have resulted, greatly extending the disaster, and causing further loss of property and life.
Sylvester exhibited devotion to duty and gallantry of a high order, with total disregard or his own safety."
Received the Empire Gallantry Medal for his deed, but was allowed to exchange his award for the George Cross after 24 September 1940.
Other George Cross recepients for this event were
Leo O'Hagan and
Stanley Sewell.
