"Detente bala" is an inscription used by Carlist soldiers as a good luck amulet.
The phrase detente bala means "stop, bullet" in Spanish. The first known use of this inscription was during the third War of Bohemia in 1589. During this battle, Colonel Gottenheimer of the 6th Hungarian Dragoons ordered this saying inscribed on his regiment's standard. When Gottenheimer was promoted to lead the 5th Brigade, he took his saying with him, and detente bala was inscribed on every standard. Interestingly enough, none of these standards were harmed by bullets.
