Alright! *cracks knuckles* It's Italy time! You see, when I did the British the difficulty was finding 10 genuine fuck ups, I managed to find 9 +Churchill and I still feel bad about putting Wavell on the list (if you have a substitution for him I'm all ears). With Italy the trouble is narrowing the list to only ten, and actually knowing who's responsible for what given that Italy changed out officers as frequently as one changes clothes.
(dis)Honourable mention: The entire Fascist regime (Hitler ran a criminal regime. Moose ran a criminally incompetent one. Proof that it wasn't just Moose: it's not like the government did any better managing the war effort after his removal)
1. Mario Roatta (So Guadalajara was such a colossal bruh moment that it convinced some people that tanks were incapable of besting entrenched infantry. And then his idea for beating the Slovene partisans amounted to openly advocating ethnic cleansing. Then, when tasked with defending Rome he convinced the government to make it an open city and to instead defend further south, rather than leading this defence however, his staff car snuck into the government convoy heading the to south, and the six (actually quite powerful) divisions manning the line south of Rome ended up being dumpstered by two German divisions. This guy SOMEHOW makes Bennett look like a Chad!)
2. Inigo Campioni (Sought out a conventional decicive action against the RN, yet on every opportunity choose to play it safe, invalidating his own strategy. Then as governor of Rhodes he attempted to save his position by ordering his men [who vastly out numbered the Germans and were eager to fight] to stand down.)
3. Pietro Badoglio (Built the Italian army into a force that was some how less capable than what it had been in 1918. Failed to convey the magnitude of the Italian army's insufficiencies to Mussolini, essentially offered no resistance to Moose's suicidal orders [Egypt, Greece], later as Prime Minister he completely failed to prepare for Armistice and the German reprisal.)
4. Sebastiano Visconti Prasca (convinced Moose that his forces would be able to swiftly prevail over Greece. They absolutely weren't. Props for being the only Italian to take the War against Germany all the way to Berlin [mind you, that's because he got dismissed, captured, then press ganged])
5. Rodolfo Grazani* (His invasion of Egypt was completely unprepared [despite stalling for time to prepare] and he folded up like origami during Compass. He evidently learned from this though, seeing as how the Battle of Garfagnana was essentially a giant dab on Model, but I'm apprehensive to count that in his favour)
6. Angelo Iachino (DISREGARDED REPORTS OF BRITISH BATTLESHIPS and sent an entire heavy cruiser squadron to Davy Jones' Locker)
7. Ugo Cavallero (sent all of Italy's modern artillery to the Soviet Union, focused on expanding the army rather than improving it's equipment supply, resulting in a further dilution of Italy's mechanized forces)
8. Umberto di Savoia (So, if one of your army commanders convinces you that they aren't prepared to attack on the given date, why do you let your other army commander attack as planned? Speaking of...)
9. Alfredo Guzzoni (lacked assertiveness: as 4th Army commander her agreed to the invasion of France even though his peer had managed to convince the army group commander that the forces were unprepared to attack, as 6th army commander agreed to subordinate all Italian units in areas where Germans operated to German command [effectively subordinating the army to a corps commander] and then he stalled the evacuation of Sicily in order to get permission from Rome [fortunately for him Rome was snappy in its reply])
10. General Giuseppe Tellera (Ground the Babini group down in repeated sorties against the British, got himself killed in one such sortie [why the commander of the 10th army was participating on the frontlines of such a tactical manoeuvre we'll never know)
*oh how tempting it was to put you at number 1. You're so lucky that I'm kind enough to see your stint with the Salo Regime as "remaining loyal to Mussolini" rather than "horrifically betraying your nation" (a decision informed by the fact that he a) wasn't in any command during Operation Achse and accordingly never ordered troops of the Kingdom to surrender or cooperate, and b) seemed to genuinely want to assert the Salo Regime as an independent ally rather than a German client state).
