HADLOW CHURCH STREET TQ 63 49
7/24 Hoppers Memorial approx 20m - east south east of the chancel of Church of St Mary
GV II
Memorial to 30 hop pickers who drowned in 1853. Sandstone ashlar. Short obelisk on a projecting base. The square section shaft below has a moulded base on a one-step plinth which has sockets for iron area railings. It is inscribed in capital letters around the sides of the base. On the southern side the inscription reads:
This Monument was erected by public subscription in memory of the Thirty hop pickers who were drowned at the Hart Lake Bridge in a flood of the River Medway on the 20th October, 1853, and whose bodies were buried in this churchard. In the midst of life we are in death.
The other 3 sides list their names and ages. Their ages ranged from 18-50 years along with 4 infants under 6 years old, and included 16 members of the Leatherhead family.
Apparently the hop pickers were in a cart. The horse got into difficulties on the bridge and they were swept into the swollen river. There were 11 survivors.
