The Teutonic Order took on their challenge from Konrad of Mazovia slowly. With a long history of being Crusaders, their strong point was discipline and persistence, and the beginnings in this new mission were quite humble. In 1230, a few knights established their first stronghold, called Bird’s Song, in the canopy of a giant oak tree. There they survived Prussian attacks and waited for reinforcement.
Soon, they conquered their first Prussian tribe. Its leader, Pipin, converted to Christianity, but later continued to resist the invaders. He was treated to an old Germanic punishment, mentioned in Tacitus’s Germania. The knights split his belly, spiked his entrails to a tree and flogged him. He apparently ran around it, wrapping his guts around the tree.
Pragmatic and efficient, the Crusaders understood the rules of psychological warfare. Being outnumbered, they had to scare their opponents to death. For example, during First Crusade, one of it’s leaders, a Frank called Beomund, would roast the bodies of Turks in their camp fires, the intention being to make Turks hiding nearby think that the Franks are cannibals. Massacres of civilians were common. In his chronicle of the First Crusade, Fulcher from Chartres mentions that the Crusaders captured a camp full of women, but did them no harm... other than pierce all their bellies with their spears.
Old Prussia was conquered step by step. First, the Crusaders would launch a reiza, or reise, a pillaging war party. This was when guests from western Europe, including England, would join in, small-scale operations being seemingly manageable even when bringing in often inexperienced fighters. After the pillaging, they would build a fort, later a stone castle, using local people as slaves. After surviving counter-attacks, they would capture new lands the following year.
