Just read about the Ottomans attempts to invade Montenegro, at point it just becomes dissapointing. They cannot do mountains

The refusal of high-spirited Montenegrin clans to pay tax any longer was the cause of the Pasha's invasion during the reign of the Hadjuk Bishop Rufim, when the Turks were driven back with heavy loss in Battle of Lješkopolje in 1604. About 1500 Montenegrin warriors attacked the Turkish camp on Lješkopolje field during the night, which counted 10.000 Ottoman soldiers.

In 1613, Arslan Pasha gathered army of over 40,000 men to attack part of Old Montenegro. Ottoman soldiers were twice as numerous as whole population of Old Montenegro. On 10 September the Montenegrins met the Turkish army, on the same spot Skenderbeg Crnojević was defeated nearly a century ago . The Montenegrins, although assisted by some neighbouring tribes, counted 4000 and were completely outnumbered. However, the Montenegrins managed to defeat the Turks. Arslan Pasha was wounded, and the heads of his second-in-command and a hundred other Turkish officers were carried off and stuck on the ramparts of Cetinje. The Ottoman troops retreated in disorder; many were drowned in the waters of the Morača. Others were killed by Montenegrin pursuers.

August 1768, they thus prepared to invade Montenegro to put an end to his rule.^([16]) The Ottomans assembled an army of 50,000 soldiers and invaded Montenegro from three different directions.^([15]) At the same time, the Montenegrin coast was blockaded by the Venetians, meaning that the country was effectively surrounded by enemies.^([16])

Šćepan himself appears to have momentarily fled his responsibilities due to the prospect of the Ottoman invasion.^([5]) The Montenegrin clans, united due to Šćepan's rule, managed to rally together an army of perhaps as many as 10,000 soldiers to defend their homeland. Miraculously, the outnumbered and quickly assembled Montenegrin force won the initial battle against the Ottoman invaders.
