Here is a trio (believed to be a complete group) to Ioan Florea Dumitru. A submariner of the NMS Marsuinul (The Mereswine/The Harbour Porpoise/Phocoena Phocoena) during Romania's "Crusade against Communism". Later an officer of the Romanian People's Navy and finally the Romanian People's Army.
Groups to Axis Submariners are rare enough to come across let alone those that were also awarded by a Communist Regime.
Dumitru participated in 100% of the combat missions of the NMS Marsuinul (1 of them), one of only three Romanian Submarines to participate in combat patrols during World War Two.
Any mention of pre-RPR awards have been removed from his RPR/RSR/RR records but he most likely got a Submariner Badge and the Medal "Crusade Against Communism" with two or three bars. He most likely ditched those in late 1944.
His Military Booklet fills in lots of information on his military career.
