Solution:The Government appointed a commission headed by Justice Sydney Rowlatt to investigate the nature of discontent and the cause of revolutionary activities. On the recommendation of the commission, the Rowlatt Act was passed in March 1919.The Act empowered the Government to arrest any person without assigning any reason or ground for the arrest, search any place without a warrant, and imprison any person without a trial.
The Rowlatt Act raised a storm of protests and a wave of popular indignation throughout the country. The Press and the Congress called it the "Black Act." There were strikes and public meetings at various places throughout the country.
At Amritsar, the arrest of Gandhiji and two prominent leaders Dr. Saifuddin Kitchlu and Dr. Satyapal aroused a wave of protests. On April 13, 1919, a peaceful and unarmed protest rally was held in the open, but enclosed ground called Jallianwala Bagh.
While the meeting was in progress, a British officer, Brigadier General Dyer, along with his troops, entered the park. Without any warning or asking the people to disperse, Brigadier General Dyer and his troops started firing at them.
The park had a small exit gate; it too was closed. In just ten minutes, about a thousand persons were killed, and many thousand wounded. The firing stopped only after the ammunition had been exhausted.
