Wellington's army - from their right flank towards their left, you see here the cavalry, the 1st, 3rd, 6th, 7th and Light Divisions, with the siege train and supports in the rear.
This army is patently smaller than the French, but then the French have to fight the Spanish as well. "Anglo-Portuguese" is surely an overly simple description of an army which also includes Hanoverians, Brunswickers, and French royalists - not to mention Scots and Irishmen. Mind you, it's probably no worse than describing their assorted opponents as "French".
It will probably be a month or two before the photo of the Spanish army appears - there's a lot of work going on in that department.
