—Description.[src]

This duel was fought between Molly Weasley and Bellatrix Lestrange, taking place in the Great Hall of Hogwarts Castle after the hour-long halt during the Battle of Hogwarts. Molly Weasley, the matriarch of the Weasley family, and Bellatrix Lestrange, one of Lord Voldemort's Death Eaters and described as his last, best lieutenant, engaged in the duel after the latter nearly killed Molly's daughter, Ginny.

After Molly cast a well-aimed lethal spell at Bellatrix, she toppled lifeless to the ground, making Voldemort scream in fury and point his wand at Mrs Weasley. Harry Potter cast a Shield Charm between the two of them, thus revealling himself and setting the stage for the duel that ended the Second Wizarding War.
