The speaker said Comrades in arms! Our most sacred duties have brought us to these uninhabited lands and demand our engaging in combat against a rabble of wretched adventurers to whom our authorities have innocently and unwisely lavished benefits that even

Mexicans did not enjoy, and who has taken possession of this vast and fertile area,

convinced that our own [problems in Mexico make] us incapable of defending our

soil. Miserable wretches! Soon they will be aware of their folly!Soldiers! Our comrades have been shamefully sacrificed at Anahuac, Goliad, and Bejar, and you are the ones destined to punish these murderers. My friends! We will march as long as the interests of the Nation that we serve demand it. The pretenders to our acres of Texas land will soon learn to their sorrow

that their reinforcements from New Orleans, Mobile, Boston, New York, and other

ports of the North – whence they never should have come – are insignificant; and

that Mexicans, generous by nature, will not leave unpunished [those who do] injury

or discredit to their country, regardless of who the aggressors may be.
According to the speaker, what mistake was made by Mexican officials?
