''According to a Gnostic legend, a war broke out in heaven among the angels, in which Michael’s legions defeated those of the Dragon. The nonpartisan angels who had been content to look on were consigned to earth, in order to make there a choice they had not been able to determine on high, one all the more arduous in that they brought with them no memory of the combat or, indeed, of their equivocal attitude.''

I've got this text from above, and, given the fact that, obviously, I'm not a native, I have quite a hard time comprehending it. I don't understand, precisely, the words in bold, I mean, individually I do understand them all, but in this context I just can't come up with a correlation between them. Could someone explain it to me?
