Chak 64 RB was one of the villages in Lyallpur district that had a Sikh majority. According to the famous Punjabi poet and writer Harbhajan Singh Hundal, the news about the growing violence in both sides of Punjab was gradually trickling through the villages in his locality. The village lohars were given the task of building crude weapons for protecting the villagers. The nearby Sikh village of Bharroliawala was attacked and only few survivors managed to escape to Chak 64 RB. The attack on Bharroliawala eventually compelled everyone to plan for an escape route to India.
