Right of Conquest
Berengar spent the first shift of the night on watch, protecting the barriers of the camp as a sentry within the trenches. The use of a trench line supported by sandbags and barbed wire was an invention that would normally not exist until the late 19th century. However, with his past life's memory as a combat engineer, Berengar developed such a defensive system with ease.
Barbed wire had been used extensively in his fields to keep cattle and other domesticated livestock within the boundaries of the grazing land allotted to them. However, after the ambush on his previous encampment in Schwaz, Berengar quickly learned to utilize trench tactics. When he was resupplying in Innsbruck, he ordered a barbed wire shipment to his army.
