There's a bit of truth in that story. There was indeed (perhaps still is) an OSS "alumnae association", although there are darned few OSS vets left alive. I feel lucky enough to have been trained by a number of them when I was with CIA in the late 60's-early 70's. That group did hold annual meetings, but I cannot imagine anyone making such an announcement at the gathering, nor can I imagine that Donovan had Patton killed. Donovan himself was a war hero, one of the most decorated soldiers of WWI. Won the Medal of Honor as an officer with New York's "Fighting 69th". Donovan and the OSS did not hesitate to use dirty tricks, but the enemy was the target of those operations.
Between Bradley and Patton, the former was the shotgun man of the two. I've seen a Wilkes with Bradley's name on the stock, and documentation that he used it in England during WWII.
