The battle was not without a number of fatalities in which our favorite characters faced their unfortunate mortal end; Severus Snape, Remus Lupin, Nymphadora Tonks, Colin Creevey, Bellatrix Lestrange, Fred Weasley and Lavender Brown.
Recently author J.K. Rowling took to twitter mentioning the anniversary and her reluctance to kill off some of these characters tweeting:
It's the 16th anniversary of the Battle of Hogwarts. I'm having a moment's silence over my keyboard. I hated killing some of those people.— J.K. Rowling (@jk_rowling) May 2, 2014
