Kollaa

The Kollaa (Russian: Колласйоки, Finnish: Kollaanjoki or Kollasjoki) is a 76-kilometre (47 mi) long river in the Republic of Karelia, Russia.

Before World War II, the source of the river was a part of the Finnish municipality Suistamo and it flowed further through Suojärvi to Tulemajärvi on the Russian side.

[1] The river became part of Finnish history, as the Red Army failed to break through there.

[1] The river and area are associated with the exploits of the Finnish marksman Simo Häyhä, dubbed "the White Death",[2] the gunman with the highest number of confirmed kills in any major war.

Captain Aarne Juutilainen, dubbed "the Terror of Morocco", was also remarkable figure in the battle.
