Act also provided "that his lawful son Gavin, Lord Dalzell, shall enjoy not only all the estates but the title of Earl as if his father were dead". His death sentence was not to be carried out, nor was the forfeiture of the titles recognised in Royalist circles. The first Earl went on to fight with King Charles I at the battle of Naseby on 14 June 1645, where the Earl received some blame for the loss of the battle. King Charles, attempting to rally his men, rode forward but as he did so, the Earl seized his bridle and pulled him back, fearing for the King's safety. Lord Carnwath's action was misinterpreted by the royalist soldiers as a signal to move back, leading to a collapse of their position. The military balance then tipped decisively in favour of Parliament. The first Earl's nephew, Robert Dalzell, Member of Parliament for Dumfries, was created a baronet, of Glenae, Dumfries, on 11 April 1666, in the Baronetage of Nova Scotia. He was the son of the Honourable Sir John Dalzell, himself the younger son of the first Lord. The baronetcy was to pass from father to son, until the third Baronet succeeded as the fifth Earl of Carnwath in 1702 by virtue of the Earldom's special remainder, with the peerage titles then merging with the baronetcy. The fifth Earl was a Jacobite sympathiser and supported the Earl of Mar in favour of James Stuart, the Old Pretender, in an unsuccessful rebellion in 1715 known as the Fifteen, or Lord Mar's Revolt. For his role in the rebellion the Hanoverian government passed a Writ of Attainder for treason against Lord Carnwath in 1716. He was sentenced to death, with his titles and what then remained of the estates being forfeited. The death sentence was later to be remitted by virtue of the Indemnity Act 1717. The attainder was reversed by Act of Parliament on 26 May 1826 in favour of his grandson, Lieutenant-General Robert Alexander Dalzell and the titles were restored to him. Several of the Earls are noteworthy in their own right. The eighth Earl was reported as being the youngest Earl in Britain in 1873 at the age of fourteen. Both the eleventh and thirteenth Earls were Scottish Representative Peers in the House of Lords. Arms The Earl's coat of arms is sable, a man's body proper, i.e. the flesh-coloured silhouette
