So the [Marocchinate] (https://en.m.wikipedia.org/wiki/Marocchinate) incident occured after the commanding general Alphonse Juin delivered quite a disturbing speech to motivate his Moroccan soldiers promising that "For fifty hours you will be the absolute masters of what you will find beyond the enemy. Nobody will punish you for what you will do, nobody will ask you about what you will get up to."
I can't seem to find any information on the internet on how the Allies responded to this and it also appears that Juin wasn't even punished. Wikipedia article of Alphonse Juin somewhat defended him and claimed he instituted death penalty to anyone who raped. Any truth to to this allegation or just a propaganda by the Germans? If this is true, it is very surprising that a high ranking general wasn't reprimanded for a war crime while Patton for a less heinous slapping of a soldier.
Sorry, I'm on mobile right now so my aswer is necessarily going to be short.
I'm afraid that the allegations of rape on the part of the Moroccan troops - the first instances of which were recorded in Sicily - are very much true... what's more doubtful is the veracity of the pamphlet (the one promising "fifty hours of debauchery" that is) Juin allegedly distributed among his men, no copies of which are known or have ever surfaced.
It's rather strange; such a widely-circulated leaflet must have left some trace somewhere, not least because there are plenty of similar (and even rarer) items surviving. This is made all more suspicious by the fact that the purported text first came to light as an Italian translation of a French "original", something that leads me to believe that the pamphlet thing may have very well been a fabrication. But the marocchinate themselves, well, they certainly were not!
