It's exactly what it looks like. Spanish invasion of native lands...they were driven back because the WOMEN were fighting...dressed as they would be for their culture.

If these are supposed to be Amazon ladies-as the tag says-they'd only have one breast each. They used to cut off one breast, so that there wouldn't be anything in the way when they were using a bow and arrows.
That's a myth resulting from a false etymology. Even a MOMENT's thought will tell you nobody would modify their body instead of modifying their weapon (which, any female archer will tell you,fires just fine with both tits.)
Actualy They would cover thare brests to protect it from bowstring snaps (ouch). Since most women went around toppless in anchent times this was considerd unusual and led to rumors of them cutting off thare boobs.
