Avodah Zarah 71: Soldiers and Merchants

2 new mishnayot! (first, on the bottom of the previous daf) - when a military group enters a city in a time of peace, then when the soldiers leave, open barrels of wine are forbidden, but sealed ones are permitted. In a time of war, even the open ones are permitted, taking it as a given that during war, the soldiers would not have time to pour libations. This is a puzzle, because did they really not have time? A parallel discussion in Ketubot establishes that an army does "have time" to pursue women - in their lust. (the second mishnah) - a craftsman who is paid in wine that was used for libation -- he can ask for the actual money instead. Also, the order of operations in a Jewish merchant selling wine to an idolater - where the non-Jew must pay before handling the wine, or it's tantamount to the Jew selling libation wine. Plus, how do kinyanim - formal acts of acquisition - work for non-Jews?
