	Cossack retired to stand at Stanton, near Shifnal in Shropshire at a fee of 10 guineas for the 1853-1854 season and was sold to Mr. Boythorpe and relocated to Derbyshire in 1855. He stood as a stallion in England until 1857, when he was sold to the French Imperial Stud for 25,000 francs. The best of his offspring was Gamester, a colt who won the St Leger in 1856. Another of his sons, Alcibiade, won the Grand National in 1865.
