Image: Ordnance Survey Drawings - Portsmouth (OSD 75-3)

Description: This drawing was surveyed in 1797, the year Napoleon declared that France "must destroy the English monarchy, or expect itself to be destroyed by these intriguing and enterprising islanders… Let us concentrate all our efforts on the navy and annihilate England. That done, Europe is at our feet." The detail with which the area is surveyed reflects the danger the English establishment felt. The dockyards of Portsmouth, one of most important naval sites in Britain, are shown by red blocks. The defence fortifications of the area are clearly delineated. South Sea Castle, one of the defensive forts built on the south coast by Henry VIII, is shown in plan form..
