What percentage of native americans died as a result of the transfer of european diseases to the new world?

the first two years of american revolution was not very encouraging for the patriots since the british were far superior in sea power, arms and troops.

so, based on the research i've done. the u.s. government were always on a wild goose chase just to take down castro. he then retired his trone to his brother raul in 2008 due to some health issues. so it's obvious your answer would be:

castro had no allies from which he could receive aid.

hope this and have a fantastic day!
