in the summer of 1156 geoffrey was again making trouble for henry and henry laid siege to the castles of chinon, mirebeau, loudun and montsoreau. geoffrey was forced to yield them, and according to some sources he was able to keep loudun. henry gave geoffrey an annuity of £1500 for the other two castles. shortly after that siege ended the people of nantes deposed their count and asked king henry whom they should invite to fill the vacancy. he suggested geoffrey; the offer was made and accepted. geoffrey's county was seized by conan iv of brittany, who subsequently ceded it to henry.
