17th December 1914. 8:00 AM. Cattaro. Dalmatian Coast.
In the morning, Rear-Admiral Ronarc’h, who established his temporary headquarters at Radanovici, orders his troops to fix bayonets and to prepare for a new assault. Two Foreign Legion Battalions will seize Fort Radisevic while two fresh BILAT Battalions will advance towards Fort Goradza and Vrmac, the last lock before Cattaro itself. Ronarc’h is aware he doesn’t possess any artillery and that these two forts form a coherent and powerful defensive line, the reason why he has opted for a probe attack instead of a true assault in this case and that he has decided to use BILAT units (with condemned soldiers) instead of his Legionnaires and Naval Fusiliers.
At Cattaro, Captain Klein has actively and vigorously prepared the defence of the citadel, knowing the importance of Forts Goradza and Vrmac for both the Austrians and the French. The crews of the ships in the bay have been reduced to their minimum, resulting in the creation of two temporary sailors battalions aimed at reinforcing the two Forts while one battalion of the 14th Mountain Brigade (normally used to defend Cattaro from Montenegrin attacks coming from the North) is sent in the city to serve as a reserve in case of need.
At 8: 30 AM, the French 3rd Squadron of the Line opens fire on Fort Radisevic, hoping to achieve the same result than with Fort Traste. But this time, the Austro-Hungarian ships, located behind the coastal strip and regularly informed by artillery spotters, retaliate with a growing accuracy, resulting in a couple of near misses. This forces Vice-Admiral Le Bris to order to the Vérité, République and Patrie to retaliate as well as some Naval Fusiliers in the ruins of Fort Traste can observe the KUK Navy ships.
And so begins a duel between the two flotillas which lasts for several minutes. The Patrie ends to be hit once by a 240 mm shell. However, the projectile, even if it manages to partially destroy the barrel of a 165mm gun, proves to be unable to pierce the armour the battleship at medium range, resulting in minor damage and only one man killed. In exchange, the Monarch is hit once by the République, losing one of its 150mm guns and seven men while a minor fire briefly threatens its bridge before its crew puts it down. This event nevertheless convinces the Monarch-class ships to retreat as their 240mm guns are unable to seriously damage the French pre-dreadnoughts at medium or long ranges. The Radetzky proves to be a tougher challenge though. Retreating as well, and while the French observers believe for a brief moment that the duel is over, the modern semi-dreadnought then stops near the village of Bijela, more than 16000 metres from the French battleships, and then opens fire again with its main batteries. Vice-admiral Le Bris is shocked to see splashes surrounding his ships coming from this far and tries to retaliate. But even with a maximum elevation of 12 degrees, the 305mm shells of his ships fall at least 1000 metres short from their target.
Thus virtually invulnerable, the SMS Radetzky continues to fire one salvo every two minutes, albeit with a mediocre accuracy as the Austro-Hungarian gunners are not trained for this (the official rule stating that 9000 metres is the ideal distance to engage an enemy battleship). The République is hit once though, resulting in five men killed and one 165mm gun destroyed. This convinces VA Le Bris to get his ships out of range while still bombarding Fort Radisevic during their retreat.
This bombardment still partially dismantles the Austro-Hungarian fortifications and flares are sent from the land to indicate to the fleet that the Legionnaires are going to attack. The Foreign Legions units have to go across roughly 2000 metres of open terrain (with some minor slopes and reverse slopes. But as Fort Radisevic has no HMGs and only one 155mm gun (unable to fire at them as it is intended to be used against sea targets) and two heavy mortars still functional, casualties remain particularly low (mainly wounded due to isolate rifle fire and some mortar shells). Once the fort is reached, the fighting turns in favour of the French very quickly, as the hardened Legionnaires are mostly facing reservists and sailors. Fifty Austro-Hungarian soldiers still manage to escape north though, promptly reaching the beaches facing the bay of Kotor. The SMS Wien and Budapest notice their presence and steam south before sending rowboats to rescue them, their secondary armament ready to cover their retreat.
On the French side, one of the Foreign Legion Battalions’ commander has decided to send an entire company to pursue the Austro-Hungarian survivors. But as soon as the French reach the ridge dominating the beach, they’re welcomed by a hail of 150 and 70mm shells which decimate the leading sections and prompt them to take cover behind the ridge. This allows the 50 Austrian soldiers to be rescued and sent to Fort Lustica to bolster its defences.
Overall, the
whole fight has cost to the French troops 46 killed and 107 wounded (both on land and seas) while
the Austro-Hungarian have lost 61 men killed and 94 captured (including numerous wounded, mainly from Fort Radisevic).
This success convinces the Legionnaires that a quick and daring assault against Fort Lustica could succeed and thus partially dismantling the Cattaro base outer defences. A reinforced battalion then progresses along the coastal strip, taking care of using the ridges as a protection against the Monarch-class ships’ artillery.
However, both Forts Mamula and Lustica, after an intense night of working, have managed to install 14 90mm and 80mm naval guns on the eastern portions of the forts. Consequently, and even if those guns are less effective than howitzers or mortars, they can however fully protect the immediate outskirts of the forts. Once again, when in sight, a hail of medium shells pounds the approaching French columns, inflicting heavy casualties within minutes. This fruitless assault forces the Legionnaires to fall back, after
losing around 80 men killed and missing. The news is transmitted to RA Ronarc’h at Radisevic, who reprimands the Foreign Legion battalion’s commander for such an unauthorized initiative but also contacts VA Le Bris late in the morning to inform him that without naval support, the landing troops won’t be able to progress beyond Fort Radisevic. To what VA Le Bris replies that the presence of the SMS Radetzky constitutes a threat to his ships, due to its superior armament, and that he won’t risk them again unless he’s ordered to. In the meantime, he strongly advises Ronarc’h to adopt a defensive posture in the area and to reinforce his recent gains.
While the fighting around Radisevic occurred, the BILAT battalions were launching their own probe attack against Fort Goradza. Once again, without proper artillery support and caught between the howitzers and HMGs coming from Forts Goradza and Fort Vrmac, the BILAT units suffer grievous losses during a daring charge and then retreat towards Radisevic at midday, having suffered
140 killed and missing and 70 wounded. All of this happened in spite of a diversionary attack launched by Montenegrin troops against the Forts north of Risan. Here, the well-trained Austro-Hungarian mountain troops easily repel the assault, although the number of casualties remained low on both sides.
All these assaults lead to an official instruction coming from RA Ronarc’h: until further notice, any action will be limited to reconnaissance patrols as well as sniping actions and artillery spotting. Once again, Ronarc’h requests to Le Bris that at least one battleship anchors between Zagora and Budva in order to act as a distant moving artillery battery until a proper solution can be found. At 1: PM, Le Bris accepts the request and dispatches the
Patrie to act as such.
At the beginning of the afternoon, and after 12 hours of fighting, the situation is as follows: after a moment of surprise and disorganization, the Austro-Hungarian defence of Cattaro had gained in coherence and efficiency, leading to a temporary stalemate, although the naval base is practically useless for now, with its main ships trapped in the bay. On the French side, Both Ronarc’h and Le Bris know that the situation won’t evolve unless more men and particularly heavy material are involved (a decision which wasn’t deemed to happen, according to the initial plan), hence a cautious wait-and-see approach for now.
In the meantime, both Pula and the Franco-British Fleet southeast of Cattaro are receiving a succession of detailed reports.
Losses so far (including the Army and the Navy):
-France: Roughly 400 killed and missing, 50 captured, 400 wounded.
