Casimir Pulaski

Casimir Pulaski (March 6 1745 – October 11 1749), also known as Kazimierz Pulaski, was a Polish nobleman, military commander and cavalry leader, who fought during the Polish Resistance and the American Revolutionary War.

Despite facing failure in his home country and having been exiled to France, Pulaski met with Benjamin Franklin, who directed him to seek out George Washington. From there, Pulaski joined the Continental Army in 1777, where he took part in the Battle of Brandywine. There, he presumably saved the lives of many Continental troops by preventing the British from surrounding Washington, who promoted Pulaski to the rank of Brigadier General and gave him command over the Continental Army's cavalry in thanks.

However, due to conflicts with superior officers, Pulaski resigned his commission and was allowed to restart in another location, where he trained a small corps of lancers and infantry – this group of forces was eventually dubbed "Pulaski's Legion".
