"16. I visited Kalshira and one or two neighbouring villages on the 28th February 1950. The S.P., Khulna and some of the prominent League leaders of the district were with me. When I came to the village Kalshira, I found the place desolate and in ruins. I was told in the presence of S.P. that there were 350 homesteads in this village, of these, only three had been spared and the rest had been demolished. Country boats and heads of cattle belonging to the Namasudras had been all taken away. I reported these facts to the Chief Minister, Chief Secretary and Inspector of General of Police of East Bengal and to you."
