Lala Lajpat Rai injured in police lathi charge during Simon Commission protest

In 1927, the British Parliament appointed the Indian Statutory Commission, universally known as the Simon Commission, to review the working of constitutional reforms in British India. Composed entirely of seven British parliamentarians without a single Indian member, the commission sparked widespread indignation across political factions in India. Major political organizations, including the Indian National Congress and the All-India Muslim League, called for a complete boycott of the commission wherever it traveled. When the commission prepared to visit Lahore on October 30, 1928, nationalist leaders organized a massive peaceful demonstration outside the Lahore Railway Station to greet the commissioners with black flags and slogans of "Simon Go Back."

The non-violent crowd was led by the venerable nationalist leader Lala Lajpat Rai, affectionately known as 'Punjab Kesari' (The Lion of Punjab), alongside prominent leaders like Pandit Madan Mohan Malaviya. To prevent the demonstrators from reaching the station platform, the British colonial authorities set up heavy barricades and deployed a large police force under James A. Scott, the Senior Superintendent of Police, and John P. Saunders, the Assistant Superintendent of Police. As the protest mounted, Police Superintendent Scott ordered an unprovoked lathi (baton) charge against the peaceful assembly. Scott himself personally targeted Lala Lajpat Rai, striking the sixty-three-year-old leader repeatedly on his chest and head with a wooden baton, despite Rai offering no physical resistance.

Although gravely wounded and bleeding, Rai demonstrated immense courage by addressing a massive public gathering later that evening in Lahore. In his historic speech, he proclaimed that the blows inflicted upon him would hasten the ultimate collapse of the British Raj. The deliberate violence meted out to a revered national statesman sent shockwaves throughout India, transforming political sentiment. For young revolutionaries like Bhagat Singh, Sukhdev Thapar, and Chandrashekhar Azad—who observed the police brutality—the assault represented an intolerable humiliation of the Indian nation. This brutal event directly catalyzed the radicalization of the Hindustan Socialist Republican Association (HSRA), setting in motion a violent chain of retaliatory events.
