Rajendranath Lahiri. History17/Dec/2020 Among the Kakori martyrs, the names of three â Ashfaqullah Khan, Ram Prasad Bismil and Roshan Singh â are well remembered by every Indian, mainly because they were hanged on the same date: December 19, 1927. However, the name of the fourth martyr, Rajendranath Lahiri, hanged two days before on December 17, 1927, largely remains forgotten. Lahiri can be seen as an embodiment of the transition that the Indian revolutionary movement was going through in the late 1920s.
