 Some Mexican units fought with distinction.One of the justly commemorated units was a group of six young Military College cadets (now considered Mexican national heroes), who fought to the death defending their college during the Battle of Chapultepec.The war ended with the Treaty of Guadalupe Hidalgo, which stipulated that (1) Mexico must sell its northern territories to the US for US$15 million; (2) the US would give full citizenship and voting rights, and protect the property rights of Mexicans living in the ceded territories; and (3) the US would assume $3.25 million in debt owed by Mexico to Americans.
