King Charles put into these regiments those Cavaliers who had attached themselves to him during his exile on the European continent and had fought for him at the Battle of the Dunes against the Roundheads of the Protectorate and their French allies. For political expediency he also included some of the elements of the New Model Army. The whole force consisted of two corps of horse and five or six of infantry. It is, however, on this narrow and solid basis that the structure of the English army was gradually erected. The horse consisted of two regiments the Life Guards (formed from exiled Cavaliers); and The Blues (or The Oxford Blues), formed by Lord Oxford, out of some of the best New Model Army horse regiments. The foot regiments were Grenadier Guards (initially two regiments Lord Wentworth's Regiment and John Russell's Regiment of Guards which amalgamated in 1665), the Coldstream Guards (the New Model Army regiment of General Monck), the Royal Scots (formed from the Scotch guard in France), and the Second Queen's Royals.
