Captured Film -- Germany Invades Poland 1939

The invasion of Poland gave rise to modern warfare that was literally powered by the internal combustion engine. Blitzkrieg (German, "lightning war" listen is an anglicised word describing all-motorised force concentration of tanks, infantry, artillery, combat engineers and air power, concentrating overwhelming force at high speed to break through enemy lines, and, once the lines are broken, proceeding without regard to its flank. Through constant motion, the blitzkrieg attempts to keep its enemy off-balance, making it difficult to respond effectively at any given point before the front has already moved on. Source: Wikipedia
