[citation needed] Ungvár was just as her sisterships leased to the Kriegsmarine of Nazi Germany in 1941 after having previously been used for commercial purposes on the Danube river.
Her Romanian escorts neared her in order to save anyone and anything they could when her highly dangerous cargo exploded, destroying Ungvár and sinking Vijelia and Viforul.
[citation needed] It is believed the cargo explosion completely destroyed Ungvár, leaving only a debris field and underwater crater with the wrecks of her escort ships Vijelia and Viforul laying close by.
[4] The film tells the story of director Zoltán Áprily's grandfather who worked as a waiter on the real Ungvár when she sank, being one of the six survivors.
[6][7] A sailor monument was also erected in Budapest in 1993 with an anchor replica of Ungvár to commemorate the lives lost in the disaster.
