Is someone able to deliver me non-biased informations about the Drake-Norris Expedition/Counter Armada/English Armada from 1589?

Dec 2019
I happened to come across Wikipedia on this subject. However, I'm not sure how accurate the information on Wikipedia is, especially since the authors of the Spanish/English articles seem to argue about whether certain English/Spanish literature sources are biased or not. But they seem to contain the most information about the event.
Besides I have some trouble to understand how the expedition went exactly and which information about the casualties on both sides is correct and what exactly the consequences were.

I hope somebody can enlighten me.
Thanks in advance.
And sorry about grammatical errors in my question. Unfortunately, English isn't my native language (and neither is Spanish).
