Thomas Arthur, comte de Lally, baron de Tollendal (January 13, 1702 – May 9, 1766) is a French General of Irish Jacobite ancestry.
Lally commands French forces, including two battalions of his own red-coated Regiment of Lally of the Irish Brigade, in India during the Seven Years' War.
After a failed attempt to capture Madras he loses the Battle of Wandiwash to British forces under Eyre Coote, then is forced to surrender the remaining French post at Pondicherry.
After a time spent as a prisoner of war in Britain, Lally voluntarily returns to France to face charges where he is beheaded for his alleged failures in India.
Ultimately the jealousies and disloyalties of other officers, together with insufficient resources and limited naval support prevented Lally from securing India for France.
In 1778, he will be publicly exonerated by Louis XVI of his alleged crime.
