The redoubt was built on the diagonal to allow two faces to cover the sea and two faces to cover inland to the other coast.
Garrison numbers and armaments is unclear, although in 1808 the work had eight cannons, presumably two on each face.
Following the Occupation of 1940, the Germans incorporated the redoubt into the Atlantic Wall, forming part of the defences for La Rochelle and La Pallice U-Boat base. They inserted a new work a Stutzpunkt, into the South facing wall, as can be seen in the photo from Google Earth. Part of the South wall was taken down and, in the recess, the primary armament was a 47mm anti-tank gun. Six machine guns were installed on the site.

I found this photograph on the Internet, showing an external tobruk near the South-East corner that I missed when I was there. I did not make a note of the photographer, sorry.
