Team tournament!

Hmm, shouldn't the retreating side retreat in such situations?

According to the rules, if a stalemate occurs, for example, one dragonfly runs away from 100 dwarves (they can't catch it), then the attacker retreats, meaning the dwarves, even though they can't be killed, leave for a fee. This method was used against thousands of skeletons; fast units were used to kill them, and, for example, one angel would fly away from 1000 skeletons.
In our situation, there probably wasn't a stalemate because, thanks to morale, it would trigger every 20 rounds. Two dryads gradually killed 7 fairies. This attack and unwillingness to retreat didn't affect the game in any way. Perhaps a time limit should be introduced for such situations, for example, no more than 20 minutes; otherwise, you can wait for morale for hours and ruin the game...
