The arrival of the Allies in Sicily and southern Italy coincided with an active volcanic period featuring activity on the part of Mt. Etna and (here) the extremely dangerous Mt. Vesuvius.  Both erupted, engulfing several villages in lava, at this time, occasioning some inconvenience to the Americans operating in the area.  Oh well - at least Vesuvius did not explode, as it has on several occasions in its time.  That could have been very inconvenient, indeed.  This somewhat less than reassuring 'photo of Vesuvius dates from 1944.  Best regards, JR.
