Even if I venture into that maze I mentioned above, it's worth to take a look at a battle about halfway between WWII and the events at Pozsony. Another pivotal encounter, a lost one from 1526, the battle of Mohács, against the Ottomans.
In the battle, while fleeing our king Louis II died, he drowned in a river. As we saw in this thread this drowning trope has a long history in battle descriptions, so this event fits right to the original topic as well (eg. >>13128 >>13129 >>13135).
Throughout the centuries both the reasons of our defeat and the king's death was highly debated, allowing the rise of theories close to stubborn myths, tropes or memes here closer to it's original meaning and not how it is casually used as a synonym of joke. The blame fell (and still falls) either onto the Habsburgs or Szapolyai (then the largest lord of the country, bit later as king János I), depending who prefers whom, but besides them also onto the whole Hungarian nobility, unanimously no matter of era, preference and political stance. I think only recent years, decades historians started to change this picture (this is a global trend, as I noticed not particular to us or this instance, like be more empathetic//, less judgemental/ towards the participants).
