Speaking on the occasion, he said the sacrifices of individuals and groups, such as those associated with the 'Silk Letter Movement', constitute a glorious chapter of India's history of freedom struggle and this needs to be acknowledged and appreciated.
"This movement was a plan to mobilise the support of the governments of Afghanistan and Turkey in organising a revolt within India to overthrow the British rule. Obaidullah Sindhi and Maulana Mahmood Hasan were two important leaders of this movement," Mukherjee said.
"In August 1916, some letters written on silk fell into British hands. It is believed that the Silk Letters confiscated by British government contained details of the provisional government of Azad Hind and its plans and a comprehensive scheme of forming an Army and getting the support of the Turkish government.
"The sacrifices of individuals and groups, such as those associated with the Silk Letter Movement, constitute a glorious chapter of India's history of freedom struggle and need to be acknowledged and appreciated. The stories of struggle need to be told and re-told to a young generation born in a free India and enjoying the fruits of liberty," he said.
He complimented the Department of Posts for bringing out the special stamp.
