Germany's blitzkrieg approach was characterized by extensive bombing early on to destroy the enemy's air capacity, railroads, communication lines and munitions dumps, followed by a massive land invasion with overwhelming numbers of troops, tanks and artillery.
Germany also quickly overran much of Europe and was victorious for more than two years by relying on a new military tactic called the "Blitzkrieg" (lightning war). Blitzkrieg tactics required the concentration of offensive weapons (such as tanks, planes, and artillery) along a narrow front.
General Jackson concluded that it was necessary for the United States to invade Spanish territory and forcibly take control of Pensacola, thereby dispersing (or killing) the Indians gathered there.
