They traveled down the mangrove coast. There they saw more rafts like the ones the 3 Inca interpreters came on. Once the Incas recognized their shore they anchored near a post now called Puerto Pizarro. The Incas were amazed at the horses and boats. The local governor welcomed them. Then they sent someone to tell the king.
When the Spanish came they also brought disease with them. It killed a lot of people and killed trusted generals. The emperor of the Incas got the sickness and died. This major event cause civil war between two brothers who were sent in line to be king.
The Spanish went home almost at the same time as everything was going on with the Incas. The went home and organized a plan to conquest the Incas. They got the permission of their queen and king then went to go conquest the Incas.
Pizzaro came back to the destruction of their civil war. He marched to the interior of the city. Atahuallpa had all of his attention on his war with his brother. He did not worry about the Spanish trying to take over, I mean they were just 160 men compared to like millions.
To the Incas surprise due to more advanced weapon and armor, the Spanish won the war and conquested the Incas. This was the end of the road for most Incas after.
