On 12 January 1918, Parliament authorised the Svinhufvud Senate to establish internal order and discipline on behalf of the state. On 15 January, Carl Gustaf Emil Mannerheim, a former Finnish general of the Imperial Russian Army, was appointed the commander-in-chief of the Civil Guards. The Senate appointed the Guards, henceforth called the White Guards, as the White Army of Finland. Mannerheim placed his Headquarters of the White Army in the Vaasa-Seinäjoki area. The White Order to engage was issued on 25 January. The Whites gained weaponry by disarming Russian garrisons during 21-28 January, in particular in southern Ostrobothnia. The Red Guards, led by Ali Aaltonen, refused to recognise the Whites' hegemony and established a military authority of their own. Aaltonen installed his headquarters in Helsinki and nicknamed it Smolna echoing the Smolny Institute, the Bolsheviks' headquarters in Petrograd. The Red Order of Revolution was issued on 26 January, and a red lantern, a symbolic indicator of the uprising, was lit in the tower of the Helsinki Workers' House. A large-scale mobilisation of the Reds began late in the evening of 27 January, with the Helsinki Red Guard and some of the Guards located along the Vyborg-Tampere railway having been activated between 23 and 26 January, in order to safeguard vital positions and escort a heavy railroad shipment of Bolshevik weapons from Petrograd to Finland. White troops tried to capture the shipment: 20-30 Finns, Red and White, died in the Battle of Kämärä at the Karelian Isthmus on 27 January 1918. The Finnish rivalry for power had culminated.. How many causalities occurred as a result of this event?
