So many new followers, so a quick intro!

My interest in COPP is from family history research that got out of control – my grandfather Jack Crane joined COPP in August 1944. I'm still 'learning as I go' (and sharing it in public as I go).
🗓️ #OTD in 1944 – #OpPostAble Day 1 – COPP's X-craft recce of Omaha Beach starts as X-20 leaves sub base HMS Dolphin in Gosport.

Five men are squeezed inside: COPP's Nigel Willmott, Bruce Ogden Smith and Logan Scott-Bowden, plus Ken Hudspeth and Bruce Enzer from X-20's crew. #NavalHistory 🧵

A flying visit today to Chatham's Royal Engineers Museum to donate some non-COPP items I'd accumulated and check out the small but perfectly formed War Winning Engineering exhibition. Had a whale of a time.

My imposter syndrome gets triggered!
...and while the discussion is limited, it is by no means shallow, even if the bays, rivers and chaungs often were). Can very happily recommend if military history/WW2 is your cup of tea. Great to see the author make good use of @coppsurvey.uk 's work as well 😎
