Following the fall of Tampere on 6 April 1918, the German Baltic Sea Division, which had landed in Finland on 3 April, advanced toward Helsinki despite objections from White Army commander Mannerheim. The Germans sought to seize the capital quickly and then push east toward the Russian border, overriding Finnish White plans to capture the city independently.
German troops and Finnish Whites fought Red Guard defenders in Helsinki over 12–13 April 1918. Rather than holding organized defensive lines, the Reds fought building by building and block by block, requiring the attackers to clear each position individually. Civilian life continued largely undisturbed during the fighting, with shops and transit operating normally.
The battle ended approximately 11 weeks of Red control over Helsinki. Nearly 500 people were killed, including around 400 Red Guard members killed in action or executed after surrender. Between 4,000 and 6,000 Red Guard members or supporters were subsequently arrested, marking a decisive shift in the Finnish Civil War toward a White and German victory.
