Numbers of large heavy rollers, themselves bullet proof, propelled from behind by motor-engines, geared very low, the driving wheel fitted with a caterpillar driving gear to grip the ground, the driver's seat armoured and a Maxim gun fitted. The object of this device would be to rol down the barbed wire by sheer weight, to give some cover to men creeping up behind and to support the advance with machine gun fire.This proposal contains the core elements of what will become the tank, and Hankey's circulation of this suggestion is one of the first steps in its development.
- The German occupation of most of Belgium and northeastern France has meant that a significant amount of industrial resources, including everything from coal mines to locomotives to river barges, is now under German control. The exploitation of these resources, however, has been problematic. As a KRA report of today notes, nobody knows who actually owns these resources, which makes coordinating their exploitation next to impossible. Private businesses in Germany proper want to secure a share of the booty for themselves, while alternatively not wanting utilization of these resources by KRA and other state agencies to, for example, drive down the price of coal in Germany. The exploitation of the occupied territories is far from a straightforward proposition, a theme that will recur in other lands conquered by Germany and ensure that it never receives the full economic benefit from its conquests.
