Shaheed Udham Singh, the avenger of Jallianwala Bagh, who was hanged on July 31, 1940, at Brixton (Pentonville) Prison, UK, had requested "Gutka Saheb" (Sikh prayer book) in his last letter before execution. The letter, dated June 7, 1940, written three days after his trial began on June 4, indicates how he knew his fate and embraced it with courage.
