Vocations and Indulgences for Warriors

My question actually stems from the video how the crusades saved Europe from the real crusades history YouTube page, guibert abbot of nogent was quoted saying that men that the laymen and warriors were given the vocation of soldier by God and it was their monastic way, I could be wrong maybe I misinterpreted it.

Found the quote As the French monk Guilbert of Nogent wrote in his twelfth century chronicle of the Crusades, “God has instituted in our time holy wars, so that the order of knights and the crowd running in its wake… might find a new way of gaining salvation. And so they are not forced to abandon secular affairs completely by choosing the monastic life or any religious profession, as used to be the custom, but can attain in some measure God’s grace while pursuing their own careers, with the liberty and in the dress to which they are accustomed.” Those who “took up the cross” were recipients of both spiritual and earthly rewards. The spiritual reward was the indulgence, or the forgiveness, of sins.

He is saying this is another way to gain heaven in fact during the Crusades those who went forward in defense of the Church and died of course would gain immediate entrance into heaven. Then those who actually left their duty as a Crusader were excommunicated and it was taught they would lose their salvation if they did not repent...good quote!

To the best of my knowledge the indulgences were meant to be restricted for the particular bull/cause. For instance a Crusade would carry indulgences if properly performed and for the Crusade.

Here is an example:
Philip II of France went on the 3rd Crusade and absconded citing "ill health", when in reality it was all a hoax as his arch-rival on Crusade, Richard the Lionheart was severely ill but chose to remain for the maximum period he could until Philip II of France along in connivance with John tried to rob Richard of his crown back home.

So did Philip II really gain an indulgence? I doubt it.

Richard did not succeed in taking Jerusalem which he could've done easily, but settled the latin coast of Outremer before departing promising to return once he settled affairs in his kingdom as it was being threatened by Philip II of France. They say he led a bad life with all sorts of criticisms. Not sure if his Crusader indulgence worked right away, but a 13th century Bishop of Rochester did say that in a dream he saw Richard entering heaven which would be good 33 years since his death. I believe in it, perhaps Richard did go to heaven because of not only his Crusader indulgence, but other things as well.
