The strategic aim of the Soviet Estonian Operation was to reoccupy Estonia as a favorable base for the invasions of Finland and East Prussia. Waffen-SS forces included 24 volunteer infantry battalions from the SS Division Nordland, the SS Division Langemarck, the SS Division Nederland, and the Walloon Legion. Roughly half of the infantry consisted of the personnel of the 20th Waffen Grenadier Division of the SS (1st Estonian) motivated to regain Estonian independence rather than support Nazi power.[9] The German force of 22,250 men held off 136,830 Soviet troops.
