Is there a specific prohibition against the consumption of meat and wine of the 9th of Av besides for the general obligation to fast?
This question makes a difference in the case of someone who is forced to break his / her fast. May said individual consume meant / wine?
I saw a story that the Brisker Rav needed to eat on the 9th of Av that fell out on Sunday. He used that opportunity to make havdalah with wine on motzaei Shabbos (the beginning of the fast). Apparently, he held that there is no prohibition to consume meant and wine onthe 9th of Av itself. What do others hold?
