What biases did Vicente Filisola display?

The correct answer to this open question is the following.

Although you did not attach any options for this question, neither further context, nor reference, we can say the following.

The biases that Vicente Filisola displayed were the following.

Filisola had never led the Mexican troops on the battlefield during the Texa Revolution. So he had no experience in this situation and one of the biases was that he assumed that he knew the territory and that was not the case. Close to the Guadalupe River, he had to march, leading the troops and heavy wagons with supplies. Unfortunately for him and his troops under the heavy rain and the muddy terrain was a logistic mistake.

The other biased was that Filisola thought that the supplies he had to send Antonio López de Santana would never be intercepted by the Texans. However, he failed again because General Sam Houston troops intercepted the cargo.
