Finland The Finnish troops consisted of the 10th Separate Company (
10.Er.K) in
Parkkina and the 5th Separate Battery (
5.Er.Ptri, four 76 mm field cannons, from year 1887) in
Liinahamari. The separate companies and batteries didn't belong to any specific division of the Finnish Army and could be placed in
ad hoc formations. The troops were part of the
Lapland Group (
Lapin Ryhmä) of the Finnish Army which had its headquarters at
Rovaniemi. The troops were later reinforced with the 11th Separate Company and a 3rd Company which wasn't part of the original mobilization plans. Also the small Reconnaissance Detachment 11 (Tiedusteluosasto 11) was added to the troops. All the troops were called Detachment Pennanen (
Osasto Pennanen, totalling under 900 men) after their commander
captain Antti Pennanen.
Soviet Union The Soviet Union had the
14th Army in the
Kola Peninsula. The army consisted of three divisions, the
104th,
52nd and the
14th, operational power totalling ca. 52,500 men. Only the 104th and 52nd Divisions took part in the field operations in Petsamo, 14th occupying Liinahamari harbour. The Soviets quickly took over the port and secured it from any third party intervention. ==The battle==
