History - Buenos Aires and the British

I saw something unusual today [2]. In the back of Santa Domingo Church and Convent on the corner of Defensa and Av. Belgrano are five flags. I think two are Argentinian standards, but the other three are from units of the British armed forces. They date back from 1806 when the British made the first of two abortive attempts to take Buenos Aires. Despite studying the period for A Level History this was the first I'd heard of it [1]. The plaques next to two of the colours said they were for 1st and 2nd Battalion 71st Regiment, which a bit of wikipedia tells me now lies within 2 SCOTS after the various amalgamations. The third claims to be Royal Marines although it appears to be disputed as to whether they are true colours. Given the importance of the colours to a regiment and the lengths they'll go to to not lose them (or failing that, get them back) seeing two or possibly three on public display surely has to be fairly rare.

Plaque reads: "Trofeo de la reconquista de Buenos Aires. 1806. Del Primer Batallon del Regimiento 71"

Apparently the British Army spent some of their time (while trying to take the city) in an area around Retiro in and around what is now Plaza San Martin. This later became a training ground for the Argentinian army and part of the park is now home to a memorial for the 649 Argentinians that died during the Falklands War.

In the centre of the city, near to the Presidential Offices in the Casa Rosa, veterans of the Falklands conflict have been camped out in the square for years (probably decades) protesting for greater benefits for those affected by the war. I think it's telling that in the UK a similar thing is also taking place with the South Atlantic Medal Association campaigning to maintain support for UK veterans (some of whom are still struggling to come to terms with their experiences) and the (at least) 95 for whom it was too much and committed suicide.

I wonder whether in thirty years time we're going to see the same thing with veterans of Iraq and Afghanistan, long after it's the done thing to wear a Help for Heroes wristband?

Notes:

1. I can still remember learning about Nelson's victory in Trafalgar in 1805, bits about the Peninsula war, the introduction of Income Tax as a temporary measure by Pitt the Younger, but maybe my lack of knowledge of anything that took part in the southern hemisphere is why I got a B...
2. Update 16/4/14: It's been pointed out that there's a lot of stuff about flags here. Any similarity with Sheldon Cooper's "Fun with Flags" is purely coincidental...
