Asterix and the Chieftain's Shield

Blurb

Asterix and the Chieftain's Shield is the eleventh volume in the Asterix comic book series, written by René Goscinny and drawn by Albert Uderzo. It was originally published as a serial in Pilote issues 399-421 in 1967.
The book is inspired by the battle of Alesia, where the Gaulish warrior chief Vercingetorix surrendered to Julius Caesar. However, only the very end of the actual battle appears in the book - the main plot concerns what happened after the battle.
This episode, like Asterix and the Cauldron, is plotted like a detective novel, with a mystery to be solved at the very end.
