Thermopylae, December 25th, 1941
The Italian army had start moving divisions from Epirus to Thessaly, back in late November. The planned movement of 7 out of the 13 Italian divisions in the Epirus front would not be complete before early January. But pressure from the Turkish government to Rome, the Turks were not particularly happy to see Smyrna being reinforced from mainland Greece, had forced the Italians to move forward their plans. The Italian Christmas offensive, or the 4th battle of Thermopylae, depending on whom you were asking begun...
Off Endau, Malaya, December 25-26th, 1941
The Prince of Wales and Hood had failed to find any of the Japanese convoys. But they had been found themselves by the Japanese 2nd Fleet with the battleships Kongo and Haruna and 4 Takao class heavy cruisers in the night of the 25th to the 26th. This too solved the problem after a fashion for admiral Phillips, his two battleships were easily superior to the Japanese ones and had radar after all, as seen from the battles against the Germans and the Italians he had every reason to be confident. After all the Japanese were not even Europeans unlike the Germans. Since he could not avoid battle he could at least take the opportunity given him by the Japanese.
Phillips should had known better, after all the Japanese had been trained by the Royal Navy. And while the Japanese did not have radar, they held in store a surprise of their own in the form of the massive Type 93 torpedo of which the four Japanese cruisers had 64 and the destroyers escorting their force nearly as many. Neither Prince of Wales nor Hood would survive the night. The Japanese would themselves lose Haruna with the cruiser Maya heavily damaged...
Gulf of Sirte, December 27th, 1941
A RAF Wellington, overflew the Italian cruisers Giovanni Delle Bande Nere and Alberico Da Barbiano as they sailed south towards Tripoli at high speed, on a resupply mission. Further east other aircraft spotted an Italian convoy of 4 merchantmen, escorted by 3 light cruisers and 9 destroyers and an even stronger Italian force of 3 battleships, 2 heavy cruisers and 10 destroyers covering it. In truth the British were well aware of the position of the Italian ships from signal intercepts but did not want to alert the Italians that their naval codes had been recently broken. Not an hour later a Regia Aeronautica Z.1007 spotted HMS Malaya escorted by 3 British and 1 Dutch destroyers sailing eastwards at the top speed the old battleship could make to link up with the Allied force out of Alexandria, Salamis, HMS Illustrious, 3 light cruisers and 8 destroyers. The heavy cruiser Lemnos with the large destroyers Themistocles and Miaoulis had split off the force a few hours earlier to try to intercept the Italian cruisers, while Force K with 3 light cruisers and 4 destroyers was coming out of Malta to attack the Italian convoy. What becomes the naval battle of Malta (for Greek and Italian historians) or the battle of the gulf of Sirte (for British ones) would soon commence.
Tactically the battle can be considered a draw. Cunningham's Alexandria force, manages to join up with the Gibraltar one before being engaged by the Italian covering force. In a hard fought engagement with Salamis and Malaya dueling Littorio, Duilio and Giulio Cesare, both allied battleships are damaged as are Duilio and Littorio and things could has turned for the worse for the Allies had Littorio not been torpedoed. With visibility worsening and having also lost the heavy cruiser Gorizia the Italians fearing a repeat of the disaster that was the night action off Cythera the retire north and the Allies, with both their battleships damaged and the light cruiser HMS Naiad and the destroyer HMS Kipling sunk fail to pursue.
Closer to the Libyan coast, commander
Vasilis Laskos wins the only clear cut Allied victory of the day when he intercepts with Lemnos, Themistocles and Miaoulis the pair of Italian light cruisers bringing supplies to Tripoli. It is an uneven fight. The two Italian ships built in 1930 in reaction to the French contre-torpilleurs are relatively small with extremely light protection, Lemnos is amongst the strongest and best protected cruisers in the world, while the two Greek destroyers are such only in name being comparable in size to the massive French Mogador class. Laskos sinks both ships with negligible damage to his own. With the ships go the 1850 tons of supplies, half of it fuel they carried.
The last action of the battle takes place as close as 20 miles off Tripoli, when the British Force K finally catches up with the Italian convoy heading there in the early evening. In the close range melee that follows the British do sink 3 out of the 4 Italian merchant ships in the convoy, only the MS Vettor Pisani makes it to Tripoli, as well as two destroyers, the newly built Saetta and the Emanuele Pessagno, with two of their cruisers HMS Penelope and HMS Aurora damaged. Then disaster strikes them, as the retreating ships enter a recently laid Italian minefield. HMS Neptune, the third cruiser in the force strikes four mines in quick succession sinking with all hands. Penelope and Aurora, strike more mines and already damaged, sink as well. And so does the destroyer HMS Kandahar. By dawn Force K has ceased to exist as an effective fighting force. But only a single supply ship has reached Tripoli...
Eleusis, December 29th, 1941
The convoy carrying the Crete Division, start leaving Eleusis under heavy escort, on the way to Smyrna. Myrina, Aliaga for the Turks, had fallen the previous day and general Sarigiannis, the commander of the Greek army in Smyrna was screaming for immediate reinforcements to stabilize the front before it was too late. Despite the pressure on Thermopylae, Pangalos had still ordered the division to Smyrna. The question was if it would get through, but the navy was mobilizing every ship it could spare including Averof and Helli to make sure the reinforcements did reach Smyrna.
Mudros, December 29th, 1941
Rauf Orbay aboard the armoured ship Fatih led the Turkish navy and an attached flotilla of Italian destroyers and torpedo boats southwards to Chios. Back in March the Greeks had beaten his navy off Lesvos. This time, the final liberation of Izmir hinged upon his fleet. And the Greek navy had taken massive casualties for its size in the past several months. No better opportunity was ever going to arise...
