I get some regular emails from britannica.com, about “this day in history”or some such thing. It is interesting some days. Other days, nothing much happenend.
August 27 was the day Mother Theresa was baptized, in 1910. Most other sources said that she was born on that day. Perhaps they were doing it on the same day at the time and place, I don’t know.
1776: During the American Revolution, British forces under General William Howe defeated George Washington and the American Continental Army in the Battle of Long Island.
And a number of other things.
However, you will see that the Encyclopedia Britannica is utterly useless, because they don’t know that I was born on August 27.
