In the Battle of Vienna, it took a whole week for the reinforcements of the Holy Roman Empire to gather, as these were forces from various powers, and it was impossible to join the battlefield without prior coordination.
Fortunately, because these nearby reinforcements attracted the attention of the Ottoman army, the latter stopped attacking Vienna, allowing the defenders of the city some respite.
Although during this preparatory period, the Ottomans, relying on their large number of troops, launched several attacks, they not only prepared ten blasting points but also sent their elite New Army Troops to the front line, trying to capture Vienna before the reinforcements arrived.
However, all these plans failed, as the morale of the defenders, boosted by the arrival of reinforcements, successfully repelled all the Ottoman attacks.
