Peter tried to bring up the main army to relieve the advance guard, but the Ottomans repulsed his troops. He withdrew the Russo-Moldavian army army into a defensive position at Stănileşti, where they entrenched. The Ottoman army rapidly surrounded this position, trapping Peter's army. The Ottomans bombarded the Russo-Moldavian camp with artillery, preventing them from reaching the Prut for water. Starving and thirsty, Peter was left with no choice but to sign a peace on Ottoman terms, which he duly did on 22 July. The Treaty of the Pruth reconfirmed in 1713 through the Treaty of Adrianople (1713), stipulated the return of Azov to the Ottomans; Taganrog and several Russian fortresses were to be demolished; and the Tsar pledged to stop interfering in the affairs of the Polish–Lithuanian Commonwealth. The Ottomans also demanded that Charles XII be granted safe passage to Sweden
