As the campaigning season of 1789 began, Koca Yusuf Pasha, Grand Vizier of the Ottoman Empire, took steps to defend the provinces of Moldavia and Wallachia.  He faced the prospect of offensives from two directions.  To the northwest lay an Austrian army of 18,000 men under Coburg.  Meanwhile, Suvorov was marching Russian troops into Moldavia from the northeast.  Yusuf Pasha determined to attack the Austrian forces before they could link up with their Russian allies.  To this end, he ordered Osman Pasha to lead an army of 30,000 men north to Focşani.  The town was an important trade center strategically located on the border between Moldavia and Wallachia.Learning of the Ottoman approach, Coburg asked his Russian counterpart for assistance.  Suvorov marched with 7,000 men.  He left his position at Buirlad on July 28 and marched 40 miles in 28 hours to reach Coburg the next day on the Siret River.. Which army had more men, the one under Coburg or the one under Osman Pasha?
