On the eve of the battle, the Russian army redeployed to the area near the village of Yakivtsi, where the second fortified camp was built on June 25, 1709. It was rectangular in shape but open at the rear, overlooking the Vorskla River. It is consisted of seventeen fortifications: two bastions, two half bastions and thirteen redans, connected with each other by 3 meter high earth ramparts. In front of all ramparts there were 3 meter deep ditches. The second fortified camp played an important role in the concentration of the entire Russian army on the eve of the Battle of Poltava and its transition from defense to the offensive on June 27, 1709.

During 1853-1854 a part of the Russian fortified camp was reconstructed by the efforts of the cadets of Poltava Petrovsky cadet school under the guidance of Ivan Kollert, an officer and a teacher of mathematics.

In the same place in 1880s a sport summer camp of the cadet school was located. A plot of land for this camp was purchased by then Poltava Bishop Illarion. Obviously due to this, the place where the fortified camp of the Russian army was located was not damaged by farm work. Some earthworks were reconstructed in 1909. After the revolution of 1917 Bolsheviks established there a concentration camp where they kept so-called “bourgeois element”

During the Battle of Poltava, Tsar Peter I was in the second fortified camp of the Russian Army. In 1973 a big granite monument (width 3.15m, height 0.74m) designed by the architect Gumich was unveiled in the place where the command post of Tsar Peter I was believed to has been located.
