Operazione C3 (Part 2)
Navy
This piece is relative to the "blue water" operations of the Navy, excluding
the actual landing operations and the landing forces, which will be
discussed in detail in another piece.
---------------------------------------------------
Situation of Regia Marina, circa June 1942
The situation is indicative only; in particular the assignments of DDs to a
particular Squadriglia were very elastic.
Apparently in June no major warship were at work (all kept ready for C3[/b]),
although some of the DDs could have been.
(Note: Italian ships of the time tended to sport very long names, as "Luigi
Amedeo di Savoia, Duca degli Abruzzi" for example. They were generally
referred to in a much shorter form).
Div. = Divisione (BB, CA & CL)
Sq. = Squadriglia (DD)
Amm.Sq. = Admiral (3-stars)
Amm.Div. = Rear Admiral
--------------------------------------------------
At Naples: Amm.Sq. Iachino (Fleet CIC), Amm.Div. Giovanola (9th Div.).
9th Div. - BB Littorio [flag], V.Veneto.
1st Sq. - DD Mitragliere, Legionario.
13th Sq. - DD Alpino, Carabiniere, Bersagliere, Fuciliere
Iachino was still under the shadow of Matapan (actually he spent the
remaining part of his life writing books supporting his conduct in that
occasion). It's probably safe to assume that, in the event of a night action
against enemy, his conduct would have been VERY cautious.
The brand-new DD Legionario was the only Italian ship fitted (since March
'42) with a working radar: a German Fu.Mo 24/40 G [De.Te. in Italian
service] with a 14 NM surface radius.
The Littorio had (since August '41) an Italian E.C.-3/bis "Gufo" [Owl]
radar, but the system was still experimental and unreliable. It was
exchanged with the fully-working version E.C.-3/ter in September '42 (17 NM
surface, 45 NM air radius).
BTW, the often-heard claim that Italian Navy was unaware of the very
existence of radar until Cape Matapan is a blatant lie, since her studies on
the topic had been started in 1936.
------------------------------------------------------------
At Taranto: Amm.Sq. Bergamini.
[but redeployed to Messina for C3[/b]]
5th Div. - BB A.Doria [flag], C.Duilio, G.Cesare.
14th Sq. - DD N.Zeno, U.Vivaldi, L.Malocello.
15th Sq. - DD L.Pancaldo, A.Pigafetta, A.Da Noli, G.Di Varazzano.
This group would be tasked with the shore bombardment. See the relevant
section for more details. It's doubtful (also considering the fuel
situation) that the AA-weak Cesare would have take part in the operation;
she was removed from active fleet at the end of '42.
But for shore bombardment and crew training, there was precious little use
for such ships. Too slow to catch a cruiser, too weak to face a battleship.
--------------------------------------------------------------
At Messina: Amm.Div. Parona.
3rd Div. - CA Gorizia [flag], Trieste, Trento, Bolzano
10th Sq. - DD Oriani, Gioberti, Maestrale, Grecale
(Trento sunk 15.6.42 by British sub Umbra)
3rd Division was the weak spot of the fleet. The flagship Gorizia - although
extremely well protected - could only make 29 knots on normal load, while
her much faster sisthrens had much thinner armour. Also, the Italian 8in
guns were higly unprecise, particularly the light mounts on the Trento-class
which suffered from vibrations induced by the machinery.
75% of the Zara-class had the misfortune to be cut to pieces by point-blank
15in fire at Cape Matapan. Against cruiser they would have been a much
thoughter nut to crack.
----------------------------------------------------------------
At Augusta: Amm.Div. De Courten.
8th Div. - CL G.Garibaldi [flag], D.d.Abruzzi, D.d'Aosta
12th Sq. - DD Ascari, Corazziere, Granatiere
Although they didn't manage to fire a single shot during the war, the
Garibaldi-class ships were considered in Italy as the best cruisers in the
Mediterranean (if not in the world): very well protected, very fast and very
precise-firing (for our standards, of course..).
These ships were the backbone of Italian Fleet during 1950s - Garibaldi was
even reconstructed as CG.
-----------------------------------------------------------------
At Cagliari: Amm.Div. Da Zara.
7th Div. - CL E.d.Savoia [flag], R.Montecuccoli, M.Attendolo
11th Sq. - DD Aviere, Geniere, Camicia Nera
Seventh Division was the elite of the Navy, period. Add to this that Da Zara
was just the only Italian admiral who shown aggressivity during the war, and
you have a potential trouble for the Royal Navy.
(Note: the Italian CL Eugenio di Savoia, the KriegsMarine CA Prinz Eugen and
the Austrian BB Prinz Eugen were all named after the same person).
----------------------------------------------------------------
Comando Squadra Sommergibili
(Submarine Squadron HQ)
Amm.Div. Legnani.
About 30-40 ready subs, mainly of the "600-tons" classes.
All operative large boats transferred to Bordeaux [Betasom] or employed as
transports.
C3[/b] plan called for two thirds of the ready subs to be placed along the 2 to
4 deg E area (line Baleares-Algers) with the remaining third along the 24 to
26 deg E area (line Crete-Tobruk).
----------------------------------------------------------------
F.N.S. - Forza Navale Speciale
(Special Naval Force - tasked with landing protection)
Amm.Sq. Tur (F.N.S. CIC & 11th Div.) - "Famagosta" beach.
Amm.Div. Biancheri (12th Div.) - "Cipro" beach.
CL Bari (ex-SMS Pillau) - [flag 11th Div.]
CL Taranto (ex-SMS Strassburg) - [flag 12th Div.]
Both CLs assigned to F.N.S. as flagship for training and rehersals only, but
not to take part in the actual C3[/b] operation.
"Escort Sloop" Procione [flag Tur for C3[/b]], Orione [flag Biancheri for C3[/b]],
Pegaso, Orsa
16th Sq. - DD N.Da Recco, A.Usodimare, Premuda [ex-Yug. Dubrovnik]
7th Sq. - DD Freccia, Dardo, Saetta
8th Sq. - DD Folgore, Lampo, Strale
3rd Sq. - DD Crispi, Sella, Lubiana [ex-Yug. Ljubljana]
4th Sq. - DD Euro, Turbine, Sebenico [ex-Yug. Beograd]
(DD Usodimare sunk in error by Italian sub Alagi on 8.6.42)
plus about:
20 torpedo boats [mix of Spica-class and "three-pipes" ships]
20-30 M.S., M.A.S. & V.A.S.
M.A.S. = the classic small torpedo unit (2x450mm torps, 1x20/65, 40+ knots).
M.S. = bigger version, derived from captured ex-Yugoslavian boats,
themselves derived from German S-booten (2x533mm & 2x450mm torps, 2x20/65,
30+ knots).
V.A.S. = ASW version of M.S. (2x450mm torps, 2x20/65, 20 knots).
For the amphibious craft, see the landing section.
---------------------------------------------------------------------
German Forces in the Mediterranean
Adm. Weichold - "Larnaca" Beach
The official C3[/b] plan doesn't provide detailed ship info, but for the fact
that such landing would have been directed by Admiral Weichold (ex-liason
officer of KriegsMarine with Regia Marina HQ, and now CIC of German Forces
in the Med).
It's probable that the flagship would have been the DD ZG3 Hermes [ex-Greek
V.Georgios], the only "big" German ship around.
While apparently this command was created only for political and/or courtesy
reasons, the puzzling thing is: "Larnaca" was by far the most dangerous
beach of C3[/b] !! I suppose that the poor Weichold had accepted such "courtesy"
just for pride.
---------------------------------------------------------------
Other local forces, assigned to traffic protection routine
In Sicily:
10 torpedo boats
30-40 M.S., M.A.S. & V.A.S.
In Greece and Aegean:
10 torpedo boats
25-30 M.S., M.A.S. & V.A.S.
-----------------------------------------------------------------
Other Navy major assets
CV Aquila - at Genova, under conversion (never completed).
BB C.d.Cavour - at Trieste, under reconstruction (never completed).
CL R.Cadorna - Schoolship in Adriatic.
BB Roma - at Genova, in training, to go to 9th Div.
CL A.Regolo - as above, to 8th Div.
DD Corsaro, Bombardiere, Velite - as above, to 1st Sq.
----------------------------------------------------------------------
Shore bombardment
[see the landing section for more info]
According to C3[/b] plan, only a single coastal artillery installation could
fire against "Famagosta" beach. This was the Benghaisa Fort (at the extreme
SE corner of the island). Its armament was estimated by C3[/b] plan at "two big
guns in cavern installation, plus fifteen small ones".
5th Division was tasked with the silencing of such fort. The ships (Doria,
Duilio and maybe Cesare, plus DDs) would have to be exposed to the minimum
possible danger, firing from the maximum distance. The start of the action
was scheduled at 18.00 of X-day (06.00 of X-day being the invasion start),
approching the coast from SW with the sun behind to disrupt land fire.
It was expected to fire 10 "first charge" shells (26,000 metres range) from
each gun, followed by 20 "second charge" shells (21,000 metres range) from
each gun.
If the enemy main guns had been silenced, the BBs would then shift the fire
against the nearby Hal Far airport, while the DDs would have approached at
10,000 metres and fired about 20 shells per gun against the coastal
defences.
The operations would have shortly preceded, and somewhat covered, the
landing on the nearby "Larnaca" beach.
-------------------------------------------------------------------------
Navy problem 1 - Gunnery
Italian Navy was plagued by very poor firing precision during the war. The
main reasons are:
a) - But for BBs and "new generation" CLs (Garibaldi and Capitani Romani
classes), all twin gun mounts were of the common-cradle version, with
insufficient space between gun bores. Also, such mounts were usually very
light built.
b) - The 152/53 mounts of the old CLs (Mod.1926 & Mod.1929) were highly
automated for the time - i.e. unreliable. The subsequent 152/55 and 135/45
were more dependant on hand-power, and were very successful.
c) - The Navy had a tradition of paying premiums to gun builders if the gun
reached a muzzle velocity higher than expected. As a result the 152/53 just
missed 1,000 m/sec during firing trials, which AFAIK was (and maybe still
is) a record for naval guns. This turned into extreme wear of the bores.
e) - The directors were poor. The computer mounted on Littorio-class had a
reaction time of 3 minutes between data input and firing solution - and it
was the most sophisticate afloat. Against fast and maneuvrable targets they
were of little use. Also, all guns but the excellent 90/50 weren't
director-controlled, but used a follow-the-pointer firing system.
f) - The allowed tolerance on the weight of projectiles and firing charges
was as high as +/- 1%. This turned into high dispersion. As a result,
Italian ships invariably straddled the target from the first salvo !! This,
at first, could be taken for good firing - IIRC Cunningham at Punta Stilo
thought just that. As a comparison, the ex-German 15cm L45 (149/43 in Italy)
had an average dispersion of 50m when employing original ammo; 500m
(ten-fold) with Italian-built ammo.
The puzzling question is: why nothing was done ? IMO the Navy was well aware
of its limitations, but reputed that such problems were common abroad too.
So, the Royal Navy's gunnery precision was a bit of a cultural shock.
--------------------------------------------------------------------------
Navy problem 2 - Fuel
Fuel availability was _the_ big problem of the Navy at the time - bigger
still that poor firing precision. Fifth Division was removed from fight to
all purpose at the end of '42 due to lack of fuel - to the point that later
some DDs could be refuelled only using the remaining quantity in the bunkers
of the Dorias !!
According to C3[/b] plan, the invasion would have required 40,000 to 50,000 fuel
tons in total. This would have such an impact on fleet operations that BB
and cruisers were allowed _one_ sortie each only - plus the fuel burned in
port while being kept ready to move - unless Germany could provide extra
supply.

Evalutation of enemy strenght
According to C3[/b] plan, the strenght of Royal Navy in June 1942 would have
been:
At Gibraltar: 1-2 BBs/BCs, 2-3 CVs, 0-2 CAs, 2-6 CLs, 12-30 DDs.
At Alexandria: 0-2 BBs, 0-1 CVs, 0-2 CAs, 5-7 CLs, 15-20 DDs.
Of course, I'd like to know the actual ready units there, plus the units
available on short notice (say 5 days) in Britain and Indian Ocean during
June 1942.
Light forces (CLs and DDs) were expected to be near Malta at about 00.00 of
(X+2)-day (06.00 of X-day being the invasion start), with a permanence there
of 3 to 6 days (depending upon the agibility of La Valletta for refuelling).
It was expected that enemy BBs wouldn't have ventured in the Maltese waters,
inside the Sicily air cover.
Instead, Italian HQ was particularly worried about the possibility of a
reprisal bombing action of Force H against Genova. It was considered a more
dangerous action (for political reasons) that an attack mission against the
invasion convoy (which would have been air-covered).
Another expected British operation was a landing against the
Vichy-controlled Algeria, Tunisia and particularly Corsica, to force Italy
to redeploy its assets.
With exclusion of the 5th Div., all other major units would have been kept
in port, ready to move on short notice.
