"Their plan for Amritsar City was ambitious. They wanted to keep the City beseiged, to force Hindus and Sikhs out by arson and murder, and finally to capture two places held dear by Sikhs, and wearing a character symbolic of Sikh greatness and pride: Darbar Sahib and Khalsa College. Letters threatening destruction of these two places continued to be received by the authorities of these places from Muslims. In their confidence and feeling of being advantageously situated the Muslims did not mind declaring their plans."
