The White Company
For The White Company achievement the player must join a war against a nation that they're hiring out condottieri to. The achievement name is a reference to the medieval White Company of mercenaries (their leader, John Hawkwood, is represented on the icon).
The simplest way is to start out as a small nation that will be trampled upon by a neighboring large nation. Hire out condottieri to the larger nation for free and wait for them to declare war on you. For example, start as Byzantium and hire free condottieri to Ottomans.
The achievement does not work if you declare war on the nation that you rented condottieri to.
- I.e., the player’s country has the flag white_company.
