France Norway 1940:
Lines of Communication
In addition to the five first line Territorial Army divisions deployed to France, three second line divisions were also sent to join the British Expeditionary Force. These were the:
12 (Eastern) Infantry Division,
23 (Northumbrian) Infantry Division,
46 Infantry Division.
The first to arrive was the 12 Infantry Division on 12 April 1940, followed by the 23 Infantry Division on 22 April, and the 46 Infantry Division two days later.
None of these formations were properly trained nor equipped, and were deployed on labour and training behind the front line. When the German Army attacked, they found themselves in the path of the advancing Panzer divisions. All three formations were badly affected, with only details escaping from some units and formations.
