The tombstone of Lieutenant Gustav Adolf Sandström-Sammatti, who fell in Eastern Karelia, was unveiled near the Espoo Church on November 3, 1935.

Gustav Adolf Sandström (August 21, 1899 – April 27, 1922) took part in the Finnish War of Independence, and then completed artillery courses at an officer's school. After leaving the Finnish army, he joined the ranks of the participants of the East Karelian Uprising as a volunteer. Under the name of Sammatti, he took command of a rebel company. The company of Lieutenant Sammatti captured Kipo Village, Lendery Village and Lubosalma Village. On December 18, 1921, in Lubosalma Village, he was seriously wounded and died later in the Vyborg provincial hospital.

The granite monument, more than two meters high, with the emblem of the Finnish Union of the Kinship Warriors engraved on the polished front side, was erected by the Union of the Kinship Warriors and a number of other organizations.
