I'm a native American English speaker and this one when I first read it made me shake my head as "what did happen" sounded so odd to my ears but then I started to think about it and I actually do say "What did happen." It is only for a very specific thing though, when I'm upset... say with my children and they are saying that one thing happened and I've heard a different version or two of the same story. I would indeed say (probably through gritted teeth), "So, what DID happen???" Or I might say "So tell me, what DID happen?" At that point, my girls better tell me the truth about what happened.
Thanks I know that we can use 'do' or 'did' to emphasize the meaning or stress something. For example, I do like apples, I did see him last night, etc. But ''what happened'' was playing on my mind for a long time. I was wondering why it was not used with the auxiliary verb ''did''. Thanks to this forum and people who know more than me I could get some nice and reasonable answers
