Samana fell to Baba Banda Singh Bahadur Ji in November 1709, after Sonipat and before Sirhind.
It was chosen deliberately. Sayyed Jalal-ud-din, the executioner who beheaded Guru Tegh Bahadur Ji at Delhi, was from Samana. So were Shashal Beg and Bashal Beg, the men who carried out the killing of the younger Sahibzade at Sirhind.
The town was sacked. Contemporary Persian accounts describe very heavy killing.
Samana had been a wealthy Mughal town with a mint and it never recovered its position.
The sequence Samana, Kapuri, Sadhaura, Sirhind, between November 1709 and May 1710, is described in Sikh sources as retribution, and the targets fit that: the executioners of Guru Tegh Bahadur Ji and of Guru Gobind Singh Ji's sons at Samana, Qadam-ud-din at Kapuri, Usman Khan at Sadhaura and Wazir Khan at Sirhind. Whether the Mughal chroniclers described it the same way is not established here.
Samana is now a tehsil town in Patiala district with a grain market and a set of Mughal-period tombs and brick structures in poor condition, and no interpretation of any kind.
It was a mint town under the Delhi Sultanate and the Mughals and its coins survive in collections. That is the physical evidence for what it was before 1709.
The choice of Samana as the first target is the clearest evidence for how the campaign of 1709 and 1710 was planned: it was not the nearest town, or the richest, or the most defensible. It was where the executioners had come from.
