They failed due to poor planning and the practical problem of moving such a large force across the steppe but nonetheless played a key role in halting the Ottoman expansion in Europe.

On 18 May 1687, a Russian army of about 90,610 soldiers, led by knyaz Vasily Golitsyn, left Okhtyrka on the Belgorod Line.
On 2 June they were joined by 50,000 Left Bank Cossacks under hetman Ivan Samoilovich at the mouth of the Samora River where the Dnieper turns south.
After a few days of marching over burnt land, their horses were exhausted, they were short of water, and 130 miles from their goal at Perekop.
