Answer:
Siege.
Step-by-step explanation:
Siege is a term that best described a military blockade of a city or fort, cutting off people and supplies from coming in or leaving.
This ultimately implies that, the main purpose of a siege is to cut-off essential supplies by surrounding the region or area such as a city, town or building with military forces so as to compel the people (enemy) living in there to surrender.
For example, a siege was a military strategy used by the Santa Anna at the
Alamo between the 23rd of February, 1836 and the 6th of March, 1836. Thus, the siege used at the Battle of Alamo lasted for thirteen (13) days before the Mexican army launched an assault on the Texians and Tejanos.
