Finding the Amazons in Herodotus

In Herodotus's "Histories", (Waterfield, Robin. 1998. OUP) the Amazon women are mentioned twice. The first occurs in Book Four, Section 110, and continues until Section 117.

In this passage, Herodotus begins with the capture of several Amazon women after their defeat by the Greeks at the Battle of Thermodon. The Greek warriors held the women captive in a ship as they traveled homeward. However, the women revolted and overthrew the Greeks and took control of the vessel. Unfortunately, the Amazon's did not know how to control a ship and were therefore forced to "ride it out" until they crash landed by Lake Maeetis in a country inhabited by Scythians called Cremni. The women travelled inland for awhile and eventually came upon a herd of horses. Being extrewmely well versed in husbandry, the women were able to tame the horses and take them uinder their control. The Amazons soon began robbing the native Scythian villages, and in response, the Scythians sent out a fighting force to battle the Amazons. Interestingly enough, the Scythians believed that they were going against young men, not women. However, after the battle, while they were disposing of the corpses, the Scythians realized that they were actually fighting women warriors. The Scythians sent out a band of young men to follow the Amazons and camp near to them. They were ordered not to attack, and to retreat if the women attacked them. If that hapened, they were to return to their camp and continue trying to get close to the female camp. The reason for this, explains Herodotus, was so that the men could try and have intercourse with the women and assimilate them into their society. Eventually, the two camps came closer together went the Amazon's realized that the men were not going to harm them. During the day, the Amazon women would split up into ones and two's and go away to relive themselves. One day, a Scythian man encountered a woman alone and she allowed him to have intercourse with her. They could not understand each other's language, but the Amazon made it clear to him that the next day he should bring one of his friends and she would bring another woman.
After that, the men and women formed couples and lived in relative harmony. The women learned to speak Scythian. The men invited their new wives to go back home with them, but the women refused because they were not versed in the traditional ways of women. They were instead comfortable with archery, husbandry, and warfare. So the men went home and gathered their share of property and traveled away with their new wives to start a new community.

Other things to note from Herodotus:
The Amazon women were also called "Sauromatae", or "Sarmatian"
The Scythians called the Amazon women Oeorpata, which means "Killers of Men"
A young woman was not allowed to marry until she had killed a male enemy.

Herodotus also mentions Amazons in Book 9 Section 27.
All it says here is that the Amazons came from the River Thermodon and invaded Attica.
