FSG Members may be interested in this Helion Conference which says it will consider Britain’s mixed record in the field of amphibious warfare, looking at what made some operations successful while others ended in disaster. Eight speakers examine campaigns from across four continents, addressing topics from high-level planning and command relationships down to army-navy cooperation as it played out on the ground.
Whilst not a Fortifications conference clearly fortifications (or avoiding them) were often a feature in amphibious operations. Further details are available here.
