Aisne – NIVELLE OFFENSIVE (SECOND BATTLE OF THE AISNE) on 25-mile front (until April 20): Despite long preparatory bombardment and first French tank attack, from 0630 hours to nightfall 20 French divisions (6,731 infantry casualties in 3 divisions alone) have advanced c.600 yards against 15 German divisions instead of 6 miles anticipated.
Decimated by MG fire, Senegalese troops break and flee. Fifth Army’s 128 Schneider tanks bog down (32 knocked out), only few reach German third line. French losses up to c.100,000 instead of 15,000 planned for.
Nivelle belatedly confines effort to either flank of Chemin des Dames. Forewarned, Germans have inserted new First Army (F Below) from Somme between Third and Seventh Armies on the front of attack.
Artois: Haig and his army commanders meet to plan next assault.
Germany: Strikes (until April 23) in Berlin (217,000 workers) and Leipzig against bread ration cut (April 15).
Russia: Lenin arrives at Petrograd; makes ‘April Theses‘ on April 17 speech to Petrograd Soviet.
USA: Shipping Board’s Emergency Fleet chartered, 280,000 shipyard workers enrolled by April 20.
