How might the Mongols utilize the Russian duke's description during a potential invasion of Hungary?

The Mongols could use the Russian duke's description to instill fear and intimidate the Hungarians into surrendering. By leveraging the accounts of the duke, which may highlight the ferocity, military prowess, and ruthless tactics of the Mongols during their invasions, they could create a psychological disadvantage for the Hungarian defenders. Fear of devastating consequences often leads to hastened surrenders, as people may prefer to capitulate rather than face violent conflict and destruction. This tactic of intimidation has historically been an effective strategy in warfare, as showcasing strength and a fearsome reputation can diminish the resolve of potential adversaries. The other options, while they may carry some theoretical merit, do not specifically align with the strategic advantage that would come from using intimidation as a primary tactic in a military context.
