Sirius Black's break-in of Hogwarts Castle (1994)

The 1994 Sirius Black Knife Attack took place the night after Gryffindor's win over Ravenclaw, promoting them to the Quidditch Cup Final.

The Attack
The Attack took place around 1:00am the morning after Gryffindor's win over Ravenclaw, promoting them to the Quidditch Cup. Harry Potter, Ron Weasley, Neville Longbottom, Dean Thomas & Seamus Finnigan were all asleep after the evening's celebrations, when Sirius Black was able to enter the Gryffindor Common Room after finding a piece of paper owned by Neville Longbottom that contained all the passwords required to enter Gryffindor Tower. Black then made his way to Third Years Room & was planning on killing Peter Pettigrew who was Ron's pet rat "Scabbers." Black began slashing Weasley's curtains, aiming for Pettigrew, but Ron woke up thinking Black was about to attack him & began screaming. Black had no choice but to flee when Harry, Dean, Neville & Seamus awoke seconds later, aswell as all of Gryffindor Tower.
