One of these banners was captured by Swedish troops in Battle of Prague (1648), when they captured the western bank of the Vltava river and were repulsed from the eastern bank, they placed it in the Royal Military Museum in Stockholm; although this flag still exists, it is in very poor condition. They also took the Codex Gigas and the Codex Argenteus. The earliest evidence indicates that a gonfalon with a municipal charge painted on it was used for Old Town as early as 1419. Since this city militia flag was in use before 1477 and during the Hussite Wars, it is the oldest still preserved municipal flag of Bohemia.
