Seriously, I'm looking at articles like the Maitland Plan in Wikipedia and it looks like the British were waging this war in the stupidest way possible, disregarding completely logistics and assuming that they would win just because of the supreme might of being British (TM). They don't even seem to have a clear idea of what to do with the territories or deal with the population, calling for direct annexation once and then talking of supporting independentist armies a minute later. There is no talk of securing positions either. Apparently they believed that taking Buenos Aires was enough to march to the Andes and once in Chile, well, they could walk all the way to Ecuador without meeting the slightest resistance.
That looks like a recipe for disaster, and it was in real life. The first time they took Buenos Aires, they got kicked out by an army coming from Montevideo. The second time they took Montevideo, then got kicked out by an army coming from Buenos Aires.
You talk like there is one city lying there to take and that defence is only going to be mounted from Spain. It isn't. There is an army and militias in La Plata and armies that can be levied in Peru and Chile and send there. You say that it is hard to do that. Yet, the British plan is to do exactly that in the opposite direction, coming all the way from the sea and wrongly assuming that they have popular support and their rivals have not.
Oh, I agree that the British plan to use place after place as jumping stones for the next one until you get to Peru is ridiculous. But if we assume as taken that the British are successful in their initial invasion (potentially with a POD of a better invasion plan), than it's certainly plausible they could take and hold Montevideo and Buenos Aires for a few years. Once this happens, plans to get to Chile are obviously going to go badly, causing a retreat to the coastal Argentinian cities. But I think it is viable for the British to hold onto these cities, and slowly deal with any guerilla attacks that might happen from the countryside. A slow subjugation of the countryside East of the Andes is possible.
And yet, the last time they went to war against Portugal just some years before they won with no need of the Mighty British (TM) to save their sorry asses, while the Mighty British (TM) is not coming with an offer of self-government under the arm as far as we know.
Sorry - can you clarify what war you're talking about here? I agree that if the British do not offer some degree of voice in a political situation then it'll develop into a quagmire the British would have to eventually withdraw from. My argument is that they would follow the Canadian example, but I accept that's not inevitable.
No, but it was a small colony isolated from everything but the sea and African tribes that had no love for it. And when the British occupied it there were no Netherlands to speak of since they had been invaded by France.
Now, if the Netherlands were free at the time of the war and the whole east of Africa from Egypt to the Cape had been colonized by the Dutch for 300 years, I think they would have done something.
Spain was hardly a free country in the 1807-1814 period.
