Little Mariners at Froghole (Crockham Hill) was being used by
the LCC as a home for evacuated children, but the house was
severely damaged by incendiaries and the children and staff
moved to Weald House (now Hoplands) on the edge of Crockham
In the early hours of Friday 30 June 1944 a flying bomb (doodlebug)
came over, apparently struck a tree on Mariners Hill and was
deflected onto Weald House. Twentyone children and eight female
staff were killed in the tragedy - Kent's largest single civilian
loss during World War II.
(Oliver Fielding-Clark's autobiography,
Unfinished Conflict contains a piece about this - he was Vicar
of C Hill at the time and one of the first on the scene.)
All the victims were buried in Edenbridge churchyard, where
you can find the memorial.
