Kanbei's Error? is the eleventh mission of the Advance Wars campaign. It is the last mission in which you will face Kanbei. Clearing this mission in 12 days is the third step to obtain three additional secret missions; in doing so you will unlock Kanbei for The Final Battle! and make Sonja available for purchase in Battle Maps after clearing the campaign.
