the fortress of Azov. In July 1737, Münnich's army took by storm the Turkish fortress of Ochakov. Lacy's army (already 40,000 men strong) marched into the Crimea the same month and captured Karasubazar. However, Lacy and his troops had to leave the Crimea due to lack of supplies. The Crimean campaign of 1736 ended in Russian withdrawal into Ukraine, after an estimated 30,000 losses, only 2,000 of which were lost to war-related causes and the rest to disease, hunger and famine. In July 1737, the Habsburg monarchy entered the war against the Ottoman Empire, but was defeated a number of times, amongst others in the Battle of Banja Luka on 4 August 1737, Battle of Grocka at 18, 21–22 July 1739, and then lost Belgrade after an Ottoman siege from 18 July to September 1739. In August, Russia, Austria and Ottoman Empire began negotiations in Nemirov, which would turn out to be fruitless. There were no significant military operations in 1738. The Russian Army had to leave Ochakov and Kinburn due to the plague outbreak. According to an Ottoman Muslim account of the war translated into English by C. Fraser, Bosnian Muslim women fought in battle since they "acquired the courage of heroes" against the Austrian Germans at the siege of Osterwitch-atyk (Östroviç-i âtık) fortress. Women also fought in the defense of the fortresses of Būzin (Büzin) and Chetin (Çetin). Their bravery was described in a French account, too. Yeni Pazar, Izvornik, Gradişka, and Banaluka were also struck by the Austrians. The final stage of the war In 1739, the Russian army, commanded by Field Marshal Münnich, crossed the Dnieper, defeated the Turks at Stavuchany and occupied the fortress of Khotyn (August 19) and Iaşi. However, Austria was defeated by the Turks at Grocka and signed a separate treaty in Belgrade with the Ottoman Empire on 21 August, probably being alarmed at the prospect of Russian military success. This, coupled with the imminent threat of a Swedish invasion, and Ottoman alliances with Prussia, Poland and Sweden, forced Russia to sign the Treaty of Niš with Turkey on 29 September, which ended the war. The peace treaty granted Azov to Russia and consolidated Russia's control over the Zaporizhia. For Austria, the war proved a stunning defeat. The Russian forces were much more successful on the field, but they lost tens of thousands to disease. The loss and desertion figures for the
