The civil war period? Or De Gaulle in general? There's very little analysis of the Gaullist-OAS Civil War, largely because it was a secret, dirty little war where both sides completely threw out the rule book. Funnily enough, Frederick Forsyth - author of The Day of the Jackal, and a former journalist who reported on the war more than most - might just be the world's foremost expert on the period, and he's hardly an academic. The various government files dealing with the issue that have been released since - notably those of Germany and Italy - are very, very circumspect in how they deal with the situation (and mostly blacked out), though after De Gaulle had several high-profile OAS officers kidnapped in Germany the German files get a little, shall we say, frosty in their tone towards the Gaullists.
With the Gaullist victory, any attempt to study the period as anything other than "filthy traitors fighting against De Gaulle, embodiment of France" is out of the question in France itself, and few non-French academics have spared the period even a cursory glance, prefering to focus on the bigger Cold War picture. I've actually read more books about Algeria during the period than France. If anyone knows some decent sources on the Gaullist-OAS War, I'd be eternally grateful for them.
