Description:
Construction of Hoo and Darnet Forts was very difficult due to the instability of the ground. The original plans had to be revised, along with the original intended armament for the forts, in order for building to continue. An upper tier for each fort was scrapped entirely and the number of guns reduced from 25 to 11. As a further supporting measure, thick iron bands were placed around each fort.
