I don't remember this particular instance, but probably yes, or I must have been too exhausted to fight back at this point.
Maybe it is a bit of an outside chance it'd turn out that way for the top one on the left arm more than any other, but Meg R Strong was able to comfortably win every time with me on that side so if anyone can match ok with Anna M Strong I guess it'd be her - as I mentioned before the pro armwrestler Joanne Poole did win against Meg pretty quickly, but maybe she would win against Anna too.
So Sheena's armwrestling can be a second point of reference for Anat when Roy does get to see her, as well as his experiences with Amazon Annie of course.
