mortified

Kazuo Ishiguro氏のThe Buried Giantを読んでいます。
It happened so quickly it appeared to Axl the men had abandoned their swords and were now holding one another in a complicated and mutual armlock. As they did so, they rotated a little, like dancers, and Axl could then see that their two blades, perhaps because of the huge impact of their coming together, had become melded as one. Both men, mortified by this turn of events, were now doing their best to prise the weapons apart. But this was no easy task, and the old knight’s features were contorted with the effort.

上の小説の場面は二人の騎士が剣で戦っているところですが、相手を倒せずに互いの剣がくっついて離れなくなったのを気恥ずかしく思ったと解釈しますが、どうでしょう？

(usually used passively) To embarrass, to humiliate. To injure one's dignity.: I was so mortified I could have died right there; instead I fainted, but I swore I'd never let that happen to me again.
The Buried Giantも翻訳本があると思うのでいつか確認したい。
