"The art of concentrating strength at one point, forcing a breakthrough, rolling up and securing the flanks on either side, and then penetrating like lightning deep into his rear, before the enemy has time to react is in having complete maps and knowing how to use them."
-Field Marshall Erwin Rommel (1891-1944)
