13, Austrian-Hungarian reinforcements arrived from Pola, in the form of three active pre-dreadnought battleships, the SMS Monarch, SMS Wien, and SMS Budapest. They outgunned the Montenegrins, who nevertheless put up a fight for several weeks, with artillery duels almost daily. With the entry of France into the war, the French realised that the capture of Kotor might be beneficial to their own navy and so landed an artillery detachment of four and four naval guns under the command of Capitaine de frégate Grellier, at Antivari, on September 18–19. It took Grellier a month to move his guns inland but eventually his batteries were set up and positioned in fortifications on the south side of Mount Lovćen. On October 19, the French guns opened fire. The Austro-Hungarians called for reinforcements and on October 21, Admiral Anton Haus despatched the modern battleship SMS Radetzky. With a broadside of four guns and four guns, the Radetsky would tip the balance. Naval seaplanes had been busy taking photographs and mapping accurate positions, and at 16:27, on October 22, the battleships all opened fire. Radetsky made a number of direct hits on the guns and fortified positions on the mountain and on October 24, one of the French guns was completely knocked out. On October 26, the Radetsky opened fire before sunrise, catching the French and Montenegrins offguard, and a number of batteries and fortifications were destroyed during what was a heavy bombardment, including another French gun. By 10:00, Allied firing from Mount Lovćen had ceased. The following day the Radetsky repositioned closer to the shore and blasted the Allied positions further. Grellier conceded defeat and pulled out his remaining saveable guns. Likewise, the Montenegrins abandoned their fortifications. By November, the French High Command decided to give up its campaign to neutralize and capture Cattaro, and the Radetzky returned to Pola on December 16. In early January 1916, the Austro-Hungarian army launched an offensive into Montenegro, and the battleship Budapest was again used to assist the troops against Lovćen's renewed defences to such good effect that on the 10th, the Austro-Hungarian troops took the Lovćen Pass and the adjacent heights, where the French guns had previously been. The bombardment of Mount Lovćen played a decisive role in breaking the morale of the defenders of the mountain, and the Montenegrins requested an armistice two days later.
