Who was Henry Trengrouse?

On Wednesday we travelled out to Helston Museum to learn all about Henry Trengrouse and how he saved so many lives. For many of us, the first question was: who is Henry Trengrouse? After meeting some of the lovely staff, hearing stories, having some time to sketch many of the artefacts,  making semaphore flags- and using them to spell out SOS-  we left having learnt so much and keen to continue investigating further once we returned to school.
