The death of Montezuma occurred on the twenty-ninth or thirtieth of June; on the first of July it was determined, by Cortez and his captains in council, to retreat from the city. The preparations for that event were immediately commenced. The road to Tacuba, a town on the mainland, being the shortest, was selected as the route of departure. As the bridges crossing the several canals had been removed by the Mexicans, Cortez ordered a bridge of wood to be made, which, carried by forty men, could be laid across the ditches as necessity might require. Owing to the predictions of an astrologer, contrary to the dictates of military science, it was decided to commence the retreat at night, in as secret a manner as possible, after the Mexicans should have desisted from their daily attack upon the palace. The gold and treasure of Montezuma was brought into the great saloon, and after entrusting the fifth belonging to the King of Spain to the proper officers, Cortez gave permission to his soldiers to load themselves with the remainder, cautioning them, however, that such a burden might prove their death during the retreat, and that it would be much better to abandon it all to the enemy. Unheeding his advice, many of the soldiers loaded themselves heavily with the treasure, and were the first to fall in the pursuit that soon followed.
[A.D. 1520.] A little before midnight, on the first of July, the army of the besieged emerged from the gates of the palace. In advance went the bearers of the temporary bridge, in charge of a detachment of five hundred men; the vanguard, commanded by the indomitable Sandoval, consisted of two hundred infantry and twenty cavalry. Next came the prisoners, the servants, females and baggage, protected by a hundred infantry and several hundred of the allies; the rear-guard, containing a greater portion of the Spanish troops, was in charge of the dashing Alvarado.
