Summer War

Additionally in the Kautla Massacre, twenty civilians were murdered and many of them were tortured before being killed. The proportion of destroyed properties to murdered civilians were because the Finnish volunteer group commanded by Henn-Ants Kurg named the ‘Erna long-range reconnaissance' broke the Red Army's blockade and evacuated civilians.[2][3]

On July 6, 1941, a larger offensive happened in Vastseliina where the Forest Brothers prevented Soviet destruction of the town and trapped the extermination battalion chiefs and local communist administrators. On July 7, the Forest Brothers were able to hoist the Estonian flag in Vasteliina. Võru was subsequently liberated and the Forest Brothers had organised into the Omakaitse militia.[4]

The battle of Tartu lasted for two weeks and destroyed a large part of the city.[1] Under the leadership of Friedrich Kurg, the Forest Brothers drove the Soviets out of Tartu, behind the Pärnu River – Emajõgi River line and secured southern Estonia by July 10.^{[need quotation to verify]} The NKVD murdered 193 people in a Tartu Prison on their retreat on July 8

Alongside the battle against the partisan group and the Soviet forces and the reintroduction of the Scorched Earth policy, the NKVD committed acts of terror against the civilian population, such as burning buildings, because they were seen as co-conspirators with the partisans.[1] Thousands of other civilians were killed, while many towns, schools, services, and other buildings were burnt down. In August 1941, the whole population of Viru-Kabala were killed, including a six-day-old infant and a two year old child. The Soviets' Destruction battalions also would occasionally burn people alive.[5] Overall, the battalions killed 1,850 unarmed civilians or partisans.[6]

Among them were the libraries of Aino and Gustav Suits and Aurora and Johannes Semper.[7]
