Pack enters the army in November 1791, being commissioned as a cornet in the 14th Light Dragoons, and serves with this regiment in Flanders in 1794 as part of Francis Rawdon-Hastings‘s expedition. Transferring to the 8th Light Dragoons, he is promoted to lieutenant In March 1795 and takes part in the expedition to Quiberon Bay. He is promoted to captain in February 1796 and serves with the 5th Dragoon Guards in Ireland during the Irish Rebellion of 1798.

Promoted to lieutenant colonel in December 1800, Pack commands the 71st (Highland) Regiment of Foot and takes part in the expedition to the Cape of Good Hope in 1806. He then takes part in General John Whitelocke‘s expedition to South America and is captured after an unsuccessful attack on Montevideo. His fellow-prisoner is William Carr Beresford, later 1st Viscount Beresford, and the two men remain friends for the rest of their lives. Refusing to give their parole to General Santiago de Liniers, they escape from La Plata in a boat, meeting a British cruiser at sea. Pack later takes part in the successful attack on Montevideo on February 9, 1807.

Pack is posted to Portugal in 1808 and is present at the Battle of Roliça on August 17 and the Battle of Vimeiro on August 21.

His descendants adopted “Pack-Beresford” as their family name. He dies on July 24, 1823, at Lord Beresford’s house in Upper Wimpole Street, London.
