"...When we attempted to cross the large lake, we came under heavy attack from many giant Indians concealed behind trees. Some of our men were wounded in this conflict for which the good armor they wore did not avail. The Indians we had so far seen are all archers. They go naked, are large of body, and appear at a distance like giants. They are of admirable proportions, very spare and of great activity and strength. The bows they use are as thick as the arm, of eleven or twelve palms in length, which they discharge at two hundred paces with so great precision that they miss nothing."
One of Cortez’s scouts wrote that he saw bones of giants; he described seeing a thigh bone that was as long as he was tall.
Wow! That armor piercing effect must have been disheartening to the Spanish force.
