The 2nd Brigade, also known as the Union Brigade, commanded by Major-General Sir William Ponsonby, was so called as it consisted of an English, the 1st (The Royals); a Scottish, 2nd ('Scots Greys'); and an Irish, 6th (Inniskilling); regiment of heavy dragoons.
Den andra brigaden, även kallad ”Union brigade”, under befäl av generalmajor Sir William Ponsonby, fick sitt namn eftersom den bestod av ett engelskt, det första (The Royals), ett skotskt, det andra ('Scots Greys'), och ett Irländskt, det sjätte (Inniskilling) tungt dragonregemente.
