At the Godric's Hollow!?
On the evening of Hallowe'en in 1981,Lord Voldemort arrived at Godric's Hollow and murdered James and Lily. He murdered James first, who tried to distract the Dark Lord; unfortunately, he did not have his wand with him and was killed immediately. Voldemort then advanced on Lily, who died trying to protect Harry.Her sacrificeprevented the Killing Curse (Avarda kedavara) from working on Harry, resulting in her love for Harry becoming a barrier to protecting him. When Voldemort attempted the curse on Harry it backfired on the caster and instead of murdering Harry, Voldemort lost all his powers and his physical form was obliterated.
Voldemort was saved from death by the five Horcruxes he had made up to that point, including his diary, Gaunt's ring, Slytherin's locket, Hufflepuff's cup (Bellatrix's Gringotts vault), and Ravenclaw's diadem. Later this also included Harry himself, because a piece of Voldemort's unstable soul latched onto the only living being present. This gave him some of Voldemort's abilities such as the ability to speak Parseltongue. This event made Harry the only person to have survived the Killing Curse, thus giving him the title the "Boy Who Lived". The failed curse left alightning-bolt scar on his forehead marking him as Voldemort's equal. The scar would be a bane and also a blessing to Harry in the years to come, as it opened a telepathic link between Lord Voldemort and himself, giving each some awareness of each other's thoughts.
Rubeus Hagrid rescued Harry from the house, partially destroyed by Voldemort's faulty killing curse, and was given specific orders from Albus Dumbledore to take him to his aunt and uncle. As Hagrid left, he was intercepted by Sirius Black, a close friend of the Potters, who pleaded for Hagrid to give the baby to him, as he was the chosen guardian in the event of James and Lily's death. Hagrid refused, saying that he was under orders from Dumbledore to take Harry to his relatives. Sirius, though reluctant, relented and gave Hagrid his flying motorcycle to take Harry to Privet Drive, and left to find Peter Pettigrew, who subsequently faked his death and framed Sirius for his death and the death of twelve Muggles. Later this encounter with Hagrid was used to support the idea that Sirius Black betrayed the Potters to Voldemort.
Hagrid delivered Harry to Dumbledore late on the evening of 1 November 1981. Dumbledore left a letter of explanation to the Dursleys, but they never relayed it to Harry. Instead, Harry spent the next decade of his life in their strict and miserable home without knowing that he was a wizard.
