Reply To: Do they know that it’s the 3 Weeks?

To Zahavasdad: In 1914, Tisha B’Av was Aug. 2 (since Aug. 1 was Shabbos). The war began on July 28 with Austria declaring war on Serbia, and by Aug 4 the last of the major powers was involved with Britain declaring war on Germany. It is quite reasonable to say that the war began on Tisha B’Av. It took only a few days for all the countries to declare war, and they then proceeded to have a bloodbath in August, at the end of which they were out of ammunition and the war settled into the war of attrition for which it is infamous.
