I have just come across this, so it's all new to me, and was wondering if anyone here is familiar with the date?

What happened on the Ninth of Av?
A Historical Overview
The 9th of Av, Tisha b'Av, commemorates a list of catastrophes so severe it's clearly a day specially cursed by G‑d.
Picture this: The year is 1313 BCE. The Israelites are in the desert, recently having experienced the miraculous Exodus, and are now poised to enter the Promised Land. But first they dispatch a reconnaissance mission to assist in formulating a prudent battle strategy. The spies return on the eighth day of Av and report that the land is unconquerable. That night, the 9th of Av, the people cry. They insist that they'd rather go backThe Jews were shocked to realize that their Second Temple was destroyed the same day as the first to Egypt than be slaughtered by the Canaanites. G‑d is highly displeased by this public demonstration of distrust in His power, and consequently that generation of Israelites never enters the Holy Land. Only their children have that privilege, after wandering in the desert for another 38 years.
The First Temple was also destroyed on the 9th of Av (423 BCE). Five centuries later (in 69 CE), as the Romans drew closer to the Second Temple, ready to torch it, the Jews were shocked to realize that their Second Temple was destroyed the same day as the first.
When the Jews rebelled against Roman rule, they believed that their leader, Simon bar Kochba, would fulfill their messianic longings. But their hopes were cruelly dashed in 133 CE as the Jewish rebels were brutally butchered in the final battle at Betar. The date of the massacre? Of course—the 9th of Av!
One year after their conquest of Betar, the Romans plowed over the Temple Mount, our nation's holiest site.
The Jews were expelled from England in 1290 CE on, you guessed it, Tisha b'Av. In 1492, the Golden Age of Spain came to a close when Queen Isabella and her husband Ferdinand ordered that the Jews be banished from the land. The edict of expulsion was signed on March 31, 1492, and the Jews were given exactly four months to put their affairs in order and leave the country. The Hebrew date on which no Jew was allowed any longer to remain in the land where he had enjoyed welcome and prosperity? Oh, by now you know it—the 9th of Av.
The Jews were expelled from England in 1290 CE on, you guessed it, Tisha b'AvReady for just one more? World War II and the Holocaust, historians conclude, was actually the long drawn-out conclusion of World War I that began in 1914. And yes, amazingly enough, the First World War also began, on the Hebrew calendar, on the 9th of Av, Tisha b'Av.
What do you make of all this? Jews see this as another confirmation of the deeply held conviction that history isn't haphazard; events – even terrible ones – are part of a Divine plan and have spiritual meaning. The message of time is that everything has a rational purpose, even though we don't understand it.
