In the 13th century, the territory of Samogitians, Curonians, Prussians, and Semigallians was in a constant state of war. The offensive and protective wars prevented natural economic and cultural development. Saulė, Semba, Durbė, Karuse, Aizkraukle, Turaida, Klaipeda, and other battles; the Order marauding campaigns into the territories of Samogitians, Curonians, Prussians, and Semigallians; the campaigns and raids of Samogitians, Curonians, and Sambians into the lands already occupied by the Order; and the revolts in the Order-occupied lands occurred almost every year. All that devastated the lands of Curonians, Samogitians, Prussians, and Semigallians, undermined demography, and weakened the economic capacity of Western and Northern Baltic tribes. The advanced armament and war tactics used in the offensive campaigns by the Order forced Curonians and Samogitians to take arms and resist. The structure of the army and the fighting methods were in the process of change, because in the mid-13th century Lithuania emerged as a state which already used conscription, and the nature of the army action was often offensive. Sometimes the Lithuanian historical literature mocks at the armament of Curonians and Samogitians, and their chargers Zemaitukai are considered as horses. That is why the historians who choose never to question a single word in the chronicles by the authors who eulogize the Order sometimes face the following questions: what kinds of armament were used by Curonians and Samogitians and what their battle methods were in the 13th century, when the attacked ones bravely went to fight their conqueror the Order. We will explore those questions in the article by employing the archaeological, historical, and cultural landscape research data.
