Signs at the start of the Jallianwala Bagh complex, meant to convey the history of the place

These are the signs soon after you enter into the Jallianwala Bagh complex in Amritsar (right next to the Golden Temple), meant to explain what the memorial was built for (it was built in memory of the hundreds killed and thousands injured after troops led by the British officer General Dyer, ordered his men to fire at an unarmed congregation who were there in support of Indian independence).
