Intentionallly throwing at a batter??

[buckeyetc71]

NFHS game. Pitcher from Team A hits opposing pitcher in first inning ( I believe unintentional). However, I take notice and position myself on Team A's side of the field (first base line) between innings. When Team A takes the field I mention to the A pitcher as he's walking by me "No retaliation". He nods and we play on. In that inning he hits a batter (not the opposing pitcher). Again I believe unintentional. However, I don't want a bean ball contest so I call out both coaches and tell them that if, in my opinion, someone intentionally throws at a batter they'll be ejected along with the coach.
My question: If I believe we have intention do you eject the pitcher and coach, just the pitcher, pitcher and both coaches? Who gets run?
By the way there were more batters hit in the game. All I believe were unintentional and I had no griping from either side for not ejecting.
