The author describes an object unknown in source literature – a souvenir which may have belonged to Romuald Traugutt, the dictator of the 1863 insurrection, who is still surrounded by a living cult. It is a silver cup with the engraved initials “R.T.”, made by a goldsmith from Moscow in 1860. According to family tradition written down by Irena Sosnowska, nee Szarecka, Romuald Traugutt exchanged glasses with Franciszek Jundziłło, commander of the neighbouring district, after the victorious battle of Horki (currently in Belarus). In 1865, Jundziłło’s widow is said to have given the souvenir to Stanisław Szarecki, her godson, who was a son of one of her husband’s comrades- in arm. The cup was inherited by Stanisław’s daughter, Irena Sosnowska, who handed it down to the author of the text, Stanisław Szarecki’s great-grandson. The author investigates the consistency of the family tale with the facts, and concludes that it is highly probably true. The detachments of Traugutt and Jundziłł, both former offi cers of the tsar’s army, fought near each other, in the area in which the Szarecki family’s manor – Strzałów (currently in Belarus) – was located.
