What preparations did cortez make to recapture tenochtitlan?10 points

He isolated the island and occupied it for 90 days

Explanation:

In May 1521, one of the longest unbroken battles in history began, lasting almost 90 days. The Spaniards, with their broad coalition, launched an attack on Tenochtitlan itself - the center of the Aztec Empire.

Cuauhtemoc  ordered the general mobilization of the people, not just the military classes, and even women took up arms to defend their city. The goals were clear; After it has been eliminated  the possibility of surrender, the struggle for bare life, for every street, house and canal, was launched.

The great advantage on the side of the Spaniards and their coalition was the superior technology, which this time manifested itself in ships that very quickly became the absolute rulers of Lake Texcoco. With them, Tenochtitlán became a cut off island, with insufficient supplies of food and water. The losses on both sides were enormous, and after a while Cortés shifted most of the war burden to Tlaxcalane. Although he spared his men in this way, he found himself in an unenviable position  as far as progression goes because the Tlaxcalans  were far weaker than the Aztecs.

Also, during the war years a bunch of Spanish weapons came into the hands of the Aztecs, so now many of their warriors also had swords and steel blades on top of their spears. In addition, cannons were not much used in street fighting, while houses and barricades were designed for guerrilla warfare in which the Aztecs were masters. Rain of rocks, spears and arrows poured down every street that the Cortés men would try to advance. Due to the overall situation, establishing a permanent base within the city was extremely risky,  and the only other solution for a more permanent occupation of the city was complete  destruction. Every conquered house or temple was destroyed to the ground so that they would not fall into the Aztec hands again overnight. The fight for each alley lasted until June 30, when a larger attack was ordered by Cortés, which was on his own  ended with a general disaster  and by capturing and sacrificing more  Spaniards.

Such a moral blow  began to collapse the coalition, which  threatened complete defeat. Instead  for Cuauhtemoc to take advantage of the current  moral and return it under your own  the wing of other indigenous peoples, who  have bowed to newcomers, but have  now starting to leave, Cortés took the initiative by launching  attack against one "rebel and rebel"  tribes. This action has borne fruit and brought back some  trust in his ranks. Since then, the Spaniards have  mostly recorded success for success while at defender  efficiency was constantly declining. It's all over  August 13, when the last Aztec fort was destroyed  in Tenochtitlan, though it was weeks before the outcome of the battle  was completely clear.
