Daily Hungarian Lesson (will not be a daily thing)

I was reading somewhere that Hungarians have a similar saying to our "no use crying over spilt milk." It is, "more was lost at Mohacs." I'm not sure the history but I think it dates back to the 1500s and must have been referring to some battle...I asked my English Honors advisor, who is Hungarian, and she said it is pronounced "Mohahtsh," with the accent of the first syllable, and that it is a saying that symbolizes Hungarian optimism.
