It seems there could be some confusion around the name "Aumont" in relation to military actions in Brittany. One prominent figure associated with the name Aumont is Jean-Pierre Aumont, who was a French actor seen in the film “Assignment in Brittany.” This film does involve military themes during World War II, but it is fictional and not related to actual military actions taken by someone named Aumont in Brittany.
If you are referring to historical military actions, the Battle for Brittany in 1944 during World War II was significant, involving Allied forces targeting the region for its strategic naval bases in key locations such as Lorient, St. Nazaire, and Brest (source). However, no specific mention of a military leader named Aumont in historic actions in Brittany has been noted in the search results.
If there is any other specific context or details you can provide, I'd be happy to refine the search further.
