Attack at Godric's Hollow (1981)

The Skirmish at Godric's Hollow took place after Peter Pettigrew (Wormtail) gave away the location of the Potters to Lord Voldemort on Halloween of 1981. Lord Voldemort marched to the Potters' house on Godric's Hollow and ended up killing the Potters', but when he went to kill Harry, he met his downfall.

The Prophecy
About a year before Harry's birth, Sybill Trelawney made a prophecy to Albus Dumbledore in the Hog's Head Pub. This prophecy was overheard by the then Death Eater Severus Snape. Snape went straight to his master and told him everything he heard, but not everything the prophecy contained. When Snape realized who Voldemort thought the prohecy meant, he went to Dumbledore asked for help. The headmaster of Hogwarts School of Witchcraft and Wizardry just told him that he'd keep the whole family safe.

The Battle
"Lily, take Harry and run! I'll try and hold him off!"

- James Potter before his death

Voldemort marched down to Godric's Hollow, as James told Lily to protect Harry while he held up the Dark Lord. James put up quite a fight, but before long Voldemort had killed Harry's father.

"Stand aside, you silly girl!"

- Lord Voldemort attempting to spare Lily Potter before he kills her

Then he marched in the back room and tried to give Lily a chance. When she refused to get out of the way, Voldemort just killed her. But unknown to him, this loving sacrifice protected him. When he went to face Harry, he was destroyed and Harry was made a Horcrux.

Aftermath
Twelve years later, when Harry was attacked by dementors, he heard this skirmish.
