All the material on the /Timeline so far is from a 1923 collection of Jefferson's letters and speeches called Jefferson Davis: Constitutionalist by one [Dunbar Rowland]?. It is in the public domain.
I've edited it slightly to conform with "neutral point of view". By slightly I mean where I've said Davis fought in such-and-such a battle Rowland says he 'gallantly' fought at such-and-such a battle.
