Let us have one last look at Fuller, and see how he concludes his dissertation on Caesar as a general:

"His most critical situations . . . were: at the battle of the Sambre, at the ambush near Dijon, and at the battles of Ruspina and Munda. In each he revealed his astonishing ability to seize hold of a most desperate situation, and, through sheer force of will and faith in his own genius, transmute what to a normally able general would have been certain defeat into victory. This complete confidence in himself, whatever the circumstances might be, made him one of the greatest fighting generals of the Classical age."

Nothing here either about luck, or about Fortuna. I would not wish to cross swords with Moravius on any question regarding Latin, but I do wonder, in the quotations from Caesar that he offers in translation, how many of the instances of Fortuna (ie the goddess) could equally well have been fortuna, and on how many occasions fortuna could equally well be translated as success, as it is for instance in the Loeb edition of GW 4.26.
