Saragarhi was a communication tower between Fort Lockhart and Fort Gulistan, which were built by Maharaja Ranjit Singh in the present-day Pakistan. It was used for communications between key posts with the help of heliographic signal communication, especially using sunlight to send morse code.
It is the place where the Battle of Saragarhi took place between 21 soldiers from 36th Regiment and estimated 12,000 to 24,000 Orakzai and Afridi tribesmen. All the Sikh soldiers refused to surrender and were martyred during the battle. It took place on September 12, 1897. The day is commemorated as Saragarhi Day by the Indian Army’s 4th battalion of the Sixth Regiment.
