PROBLEM: Passage: On 19 April 1918, Detachment Brandenstein took over the town of Lahti. The German troops advanced from the east-southeast via Nastola, through the Mustankallio graveyard in Salpausselka and the Russian garrisons at Hennala. The battle was minor but strategically important as it cut the connection between the western and eastern Red Guards.

Official reports indicated 151 civilian deaths and 150 wounded; unofficial reports spoke of over 200 fatalities and between 800 and as many as 2,000 wounded. The odz uprising was neither the first nor the last disturbance in what has been described in Polish historiography as the revolution in the Kingdom of Poland various protests and strikes occurred in major Polish cities under Russian control throughout the yearbut it would be the most dramatic one. In September 1905, two PPS activists would assassinate Juliusz Karol Kunitzer, owner of the Heinzel & Kunitzer factory, known for his poor treatment of workers. Strikes in odz continued until mid-1906, when the large Russian military presence and mass layoffs of striking workers from the factories finally pacified the city. Even afterward, odz was not a peaceful city; in the years 1910-1914 it was the site of a radical, anarchist and socialist group Rewolucyjni Msciciele labeled as "the most extreme, terrorist group in the history of Poland". The uprising was reported in the international press and recognized by socialist and communist activists worldwide.
