The action off Bastia (bataille navale de Pietracorbara) was a naval engagement fought on 9 September 1943 between German vessels and Italian ships and coastal artillery. Bastia is the main port of Corsica in the Ligurian Sea. Secret negotiations between the Italian government and the Allies led to the Armistice of Cassibile (3 September 1943) and the defection of Italy from the Axis.

The Germans were suspicious of Italian intentions and devised Operation Achse, a coup against the Italian government and the disarming of the Italian armed forces. At midnight on 8/9 September, German marines attacked Bastia harbour and captured the Italian ships moored there except for the torpedo boat Aliseo. At dawn, Italian troops counter-attacked, retook the port and the German vessels sailed to avoid capture.

Aliseo attacked the German vessels as they left port and turned north; Italian coastal guns also engaged the German vessels and when the corvette Cormorano arrived it joined the engagement. Two German vessels and three Marinefährprahme (MFP, ferry barges) were sunk and two MFP were forced aground. The action was one of the first examples of Italian resistance against Nazi Germany.

Background

Corsica in 1943

Corsica was garrisoned by the VII Corps (Generale Giovanni Magli) which was short of weapons, had inadequate transport and suffered from poor morale. Order 111 CT was sent to commanders from 10–15 August and late in the month, the Army General Staff transmitted Memoria 44 to military forces outside Italy which expanded Order 111 CT preventing Italian forces from engaging in hostilities with the Germans.^[1] The Armistice of Cassibile was signed on 3 September 1943, in which the Italians withdrew from the Axis and Magli applied Memoria 44.^[2]

German forces in Corsica comprised the [Brigade Reichsführer SS] Error: {{Lang}}: invalid parameter: |3= (help), a battalion of the 15th Panzergrenadier Division, two heavy coastal artillery batteries and one of heavy anti-aircraft guns. On 7 September, General Fridolin von Senger und Etterlin arrived to take command. Magli gave assurances that the Italian garrison would continue to fight against the local resistance and not oppose the arrival of German troops from Sardinia. There were about 20,000 French Maquis on the island and the Germans suspected that many of the Italians would defect.^[2]

Operation Achse

Unternehmen Achse (Operation Axis) a German plan to forestall an Italian surrender and defection to the Allies, began on 8 September and included the evacuation of the garrison of Sardinia to Corsica. When news of the Armistice was announced on 8 September, German forces began to embark from ports on the north coast of Sardinia and land at Corsican ports on the south coast. Italian coastal gunners nearby refrained from firing on the German parties.^[3]

Prelude

Present in Bastia harbour were the Italian Ciclone-class torpedo boats Aliseo (Commander Carlo Fecia di Cossato) and Ardito, the Italian merchant ship Humanitas (7,980 GRT) and a MAS motor torpedo boat. German vessels present were the anti-submarine warfare vessels UJ 2203, UJ 2219 and five Marinefährprahme (MFPs) F366, F387, F459, F612, F623 and the motor launch FL.B.412. German Marines had prepared a surprise attack on the harbour and the Italian ships there. The Germans attacked at midnight on 8/9 September; Ardito was damaged and 70 men of her 180 crew were killed. Humanitas and the MAS boat were also damaged. Aliseo managed to cast off in time and got outside the harbour, where Cossato waited for orders. After dawn on 9 September, Italian troops counter-attacked and recaptured the port, Ardito, Humanitas and the MAS.^[4]

Action

The Italian port commander ordered Cossato to prevent the German vessels from leaving port. As the German flotilla left harbour, in column to pass through the narrow harbour mouth, the ships were bombarded by the 76 mm guns of Italian coastal batteries, damaging UJ 2203 and some of the MFPs.^[4] There was a thin fog along the coast at dawn and the German flotilla could be seen emerging from the harbour and turning north, close to the coast. The German vessels outgunned Aliceo, the two UJ craft carrying an 88 mm gun each and the barges mounting a 75 mm gun and a 37 mm or a 20 mm gun.^[5]

Aliseo closed on the German flotilla and UJ2203 opened fire, the other vessels joining in as their guns bore on Aliseo, which zig-zagged until 8,000 yd (7,300 m) from the German vessels, opening fire at 7:06 a.m.. For 25 minutes Aliseo steamed northwards, parallel to the Germans firing at a rapid rate. At 7:30 a.m. Aliseo was hit by an 88 mm shell in the engine room and brought to a stop. Damage control repaired the boiler and plugged holes to get Aliseo under way again.^[5]

The torpedo boat closed in and engaged the German vessels one after the other. At 8:20 a.m. UJ 2203, after suffering several hits, exploded with the loss of nine men killed; ten minutes later UJ 2219 was destroyed when her magazines exploded.^[5] The column of MFPs dispersed as their crews sought shelter. Machine-gun fire struck the fire director and damaged it; with the range so short, the loss of director control had little effect, the gunners on Aliseo continuing under local control.^[6]

Return-fire from German 20 mm guns inflicted only superficial damage on Aliseo and by 8:35 a.m. three of the MFPs had been sunk. Five minutes later, Aliseo engaged the other two MFPs which were carrying ammunition. Shore batteries at Marina de Pietro and the corvette Cormorano, which had arrived also fired on the MFPs and forced then to run aground. Aliseo ceased fire at 8:45 a.m. and from 10:00 and 10:50 a.m. rescued survivors and then sailed towards La Spezia before diverting to Elba, arriving during the afternoon.^[6]

Aftermath

Analysis

In 2009, Vincent O'Hara wrote that Italian naval officers were out of contact with Supermarina after it stopped broadcasting on the evening of 10 September and were ignorant of the Armistice conditions. The skirmishing with German forces at Bastia and elsewhere was conducted under individual initiative and the Italian destroyers Legionario and Alfredo Oriani sailed from Malta on 13 September to carry an American OSS detachment and supplies from Algiers to Ajaccio to assist Free French and Italian troops fighting the Germans.^[7]

Casualties

A Marinefährprahm (MFP, German naval ferry barge)

Nine men were killed on UJ2203, 160 Germans were killed in the engagement and 25 were rescued by the Italian ships.^[6] The damage suffered by Ardito later caused this ship to be left behind in Portoferraio, where she was taken over and repaired by the Germans as TA.25.^[8] The German navy reported that during the evacuation of Sardinia and Corsica it lost a J-boat, seven naval ferry barges, two anti-submarine vessels, a tug, three Siebel ferries, a peniche and three steamers of 16,943 GRT each.^[9]
