Hello I recently got the following the only clue I have is some other medals that came with it that says K.Yeo but may be a red herring the photo of the divers with limpet mines has been taken by a private person on a camera the others all say restricted on the back any help would be great I think the bridge is australia
They are all most likely from Australia. The British XE class midget subs that attacked the Myoko & Takao in Singapore, as well as the undersea phone cables running from Hong Kong. Photo 9614 is certainly from Australia, and can be found on Getty Images. Photos 9622, 9635, and 9636 are of XE4 "Exciter." She participated in Operation Sabre.

Hi I have just come across your post and photos. My granddad was on the xe4, don’t suppose you have any other photos?
