I want to know the answer to the following question:
Who was the Uruguayan revolutionary that united with others from Buenos Aires?
All the background I'm provided with is that "In 1811, the forces deployed by the Junta Grande of Buenos Aires and the gaucho forces led by Artigas started a siege of Montevideo, which had refused to obey the directives of the new authorities of the May Revolution.". Is that enough to answer the question?
Answer: no
