By the Second World War the 12 pounders were inadequate and were replaced by two very fast firing ‘twin 6 pounder’ guns. Only the emplacements survive at Drake’s Island. The gun is in Portugal.

Today @FortressStudy and @PalmerstonForts visited Drake’s Island in Plymouth Sound. Fortified since the 1500’s the Island was extensively fortified in the 1860’s for Rifle Muzzle Loading guns like these mounted in the open ‘en-barrette’ and …

@FortressStudy and @PalmerstonForts are visiting Plymouth this weekend on a study trip. First stop the beautifully restored @CrownhillFort built 1863 - 1871 as part of a line of forts to protect Plymouth from a landward attack from the north. Used by the military until the 1980’s

@James1940 in @WeHaveWaysPod you talked about Northumberland & UK anti invasion defences. If you decide to do an episode @FortressStudy has lots of info. Let us know if we can help with your research. Photo - typical Northumberland Pillbox with Dunstanburgh Castle in background

The Solent Sea Forts are important historic sites. The previous owner invested in their restoration which FSG welcomed. We hope the new owner will guarantee a viable future for these fascinating fortifications.

Nick Balmer discussed the fortified trading posts on the western coast of India with a particular focus on Tellicherry which had been colonised by the Portuguese, the Dutch and the British. The dynamics of the relationships with the local Indian rulers were well explained.
