XXI and XXIII Corps in 1940

Post by mfy4444 » 08 Oct 2018 22:50

Hello. Another one of my many questions. I am curious as to the role of 21st (XXI) Corps in the 1940 battles, and in Compass. As I understand it, at first 21st Corps was part of 10th Army and covered the frontier, with 22nd Corps backing it up. The Corps was then commanded by Lorenzo Dalmazzo. However, it seems that by September 1940 and the time of advance it was 23rd Corps, under Bergonzoli, playing the main role. My questions:

When was XXIII Corps created/deployed in North Africa?

When was Dalmazzo replaced as XXI Corps commander, and by who? (I think it happened around August?)

Was XXI Corps (or at least its headquarters staff) pulled back from the front at some point, or was it still deployed in Cyrenaica during Compass? I ask this because later XXI Corps shows up along with XX Corps (of 5th Army) as the second Italian infantry corps in Libya. However, XXIII Corps and Pitassa-Manelli's XXII Corps at Tobruk seem to disappear after being essentially wiped out by February 1941. Can anyone give insight as to what happened there? Was the later XXI Corps completely reconstructed from scratch after the Compass disaster?

As always, any answers, commentary, or additional information is much appreciated.

Regards

Pardon one typo: I meant to say X Corps was part of 5th Army, not XX Corps (which began as the CAM).

To start:

In 1937, the XX (Tripoli) e XXI (Bengasi) corpo d’armata were stood up in Libya.

Per the war plan, four metropolitane divisions were transferred to A.S. in September 1939. This triggered the creation of the X C.A., and combined with the XX C.A. formed the new 5th Armata in Tripolitania. The XXII C.A. was raised at the same time, and joined the XXI C.A. in the new 10th Armata. When the four M.V.S.N. divisions were formed in October, the XXIII C.A. was raised as part of the 5th Armata.

With the fall of France, the requirement for three corps in Tripolitana was reduced and the XXIII C.A. transferred to the 10th Armata in Cirenaica. There was some juggling of units between the corps (and the 21º aprile was disbanded).

Fates:
X C.A. - Destroyed at Alamein
XX C.A. - Temporarily renamed Comando Campo Trincerato di Tripoli on 6 February 1941. Renamed XX C.A. on 16 March 1941. Redesigned Comando della Tripolitania on 15 August 1941. A new unit was reconstituted as the XX C.A.M. on 10 September 1941. Destroyed Tunisia.
XXI C.A. - Destroyed 20 December 1940, reconstituted as the Corpo d’Armata di Investimento di Tobruk on 10 July 1941. Renamed XXI C.A. on 28 July 1941. Destroyed Tunisia.
XXII C.A. - Destroyed 23 January 1941. Reformed July 1942 in Italy.
XXIII C.A. - Destroyed 5 January 1941. Reformed June 1942 in Italy.

Hi,

Dalmazzo was replaced as XXI Corps commander by Generale di divisione (later Generale di corpo d’armata) Carlo Spatocco, the date I have is 28 August.

Best regards,

VJK
