actually no, its not difficult. the allies staged air operations from Corsica OTL with ease.
Sardinia/Corsica were secured by early November 43 & in January 44 six US & French medium bomber wings were operating from Corsica. The proportionate number of fighters there were covering Axis territory from west of Marsailles to Rome and southwards. The P47s based there could cover northern Italy in depth.
seriously, i sometimes get the feeling that, despite this being a site for alternate history, people reflexively reject any option other than what happened OTL
I think its partially too much history chanel on TV & not enough in depth reading of the books, or good quality on line text like HyperWar. I should not criticize other folks too much on this as I find I have to frequently bite my tounge and avoid posting things cause My assumptions are wrong when I check them.
This CAR Library text wiking linked is not bad. You cant expect the whole picture from any single article of book, but is a decent start.
Thanks.BTW Senger after the war in an interview suggested the next time you invade Italy do it from the top down.Napoleon said Italy is like a boot go from the top!
Better yet avoid the place entirely. By late 1943 hardly 10% of the Axis miltiary production was coming out of Italy. Whoever held the place was stuck with feeding the population, and providing coal and medical supplies for the civilians. The place was becoming a sinkhole for stratigic resources, with hindsight it would be better to let the Germans and fellow Facists pay the cost.
The whole idea of a protracted campaign up the Italian boot was ludicrous to start with. I can understand the political reason for taking/liberating Rome. ....
There was the facination with 'political' prizes. One Allied leader I'll not name described Rome as a "Glittering Prize". Some people are too easily distracted by shiny stuff I guess. But, in their defense I have to admit that after the sucessive capture of Sicilly, Tranto, Calabria, Foggia, and Naples it did look like Rome was in reach.
We also must remember Rome was very nearly abandoned to the Allies. Hitler originally favored defending northern Italy as the south was too vulnerable. He was dissuabed by Kesselring who proposed a riskier strategy of defending south of Rome. Had the first plan been carried out we would be discussing how sucessful the Allied thrust into Italy was.
As for the Cassino battles (Quiz Question: Were there four or five attacks there?) The Allied commanders overestimated the effects of their firepower, air and artillery, vs positions like those the Germans possesed. As a former career artillery guy I've become aware of some of the defects in the fire plans supporting the the Allied attacks. This goes way beyond Mark Clark, or Alexander. The Corps and Division commanders were not always correct in their estimates. I suspect even Montgomery with his detailed attention for fireplanning heavy bombardments, and precise coordination would have had trouble cracking this one.
