The Hungarian 2nd Army was already known in Hungary as "The dead army" before Stalingrad. There were few illusions about them coming home intact, if at all. The majority of the Hungarian army was deployed along the Romanian border for most of the war, expecting Romania to take advantage of the situation to backstab the country. When Romania surrendered to the Soviets and its army was turned against the Axis, the expected attack did indeed materialize.The Hungarian 2nd Army was a total writeoff... sure an army of the same name was reconstructed, but most of the manpower and all of the equipment was lost.
(the German 6th Army was also reconstructed in that fashion)
