Final answer:
During the Civil War, the shortage of goods and supplies for the Texas military was caused by the Union blockade, the focus on export crops, reduced agricultural productivity, and a lack of internal transportation.
Step-by-step explanation:
During the Civil War, several factors caused a shortage of goods and supplies for the Texas military. One reason was the Union blockade, which prevented the South from importing necessary items from the North or Europe. Smugglers did provide some supplies, but they focused more on war materials and luxury items.
Another reason for the shortages was the nature of the cotton economy. The South predominantly grew export crops, and it took time to shift to food production. Furthermore, with many men serving in the military, the agricultural economy became less productive. The lack of an internal transportation system also made it difficult to move goods around the country, resulting in food supplies rotting before reaching their intended destination.
All these factors combined contributed to the shortage of goods and supplies for the Texas military during the Civil War.
