The Ottoman army had a hard time fighting in the 14th century. They did not have a good way of fighting together. During the Battle of Kosovo, they lost many soldiers and barely won. The Janissary Corps, a special group of soldiers, was too small to make a difference. The Sultan, Murad I, was killed in the battle.
The different groups of soldiers, like the Azabs and the Akinjis, had their own problems. The Azabs had light armor and could not fight against the heavily armored Serbian soldiers. The Akinjis were good at raiding but not at traditional fighting. The Timarli Sipahi Corps was still new and had many issues. It was only because of the actions of the Sultan's son, Şehzade Bayezid, that the Ottomans won the battle.
The Ottomans learned from their mistakes and improved their way of fighting. Seven years later, they worked together and defeated the Crusader forces at the Battle of Nicopolis. The Janissaries played a crucial role in this battle, using defensive tactics like sharpened stakes and ditches to defeat the enemy's cavalry. This was a significant victory for the Ottomans, and it showed that they had become a strong and capable army. They used strategic planning and tactical maneuvers to outsmart their enemies. The Ottomans also used infantry tactics, which included the use of stakes and ditches to protect themselves from the enemy's heavy cavalry. The battle was a turning point in the history of the Ottoman army, and it marked the beginning of their rise to power.
