LEUT George Gosse, RANVR, rendered safe a new type of German oyster mine in the mud on the bed of Bremen Harbour, Germany. The following is an extract from the citation for the GC awarded to him, for the operation: ‘As it was very necessary that this type of mine should be recovered intact, it was decided to attempt to render safe the mine underwater, and on the following day LEUT Gosse dived on it. Using improvised tools he eventually succeeded in removing the primer, which was followed by a loud metallic crash. The mine was eventually lifted on the quayside, when it was found that the detonator had fired immediately the primer had been removed. During the subsequent ten days LEUT Gosse rendered safe two similar types of mines which were lying in close proximity to shipping, and in each instance the detonator fired before the mine reached the surface’. LEUT Gosse, was the only graduate of the Royal Australian Naval College to be awarded the George Cross in war.
