– fine, cold
PPCLI make a raid @ 5 am.
Fearful bombardment continues. Enemy retaliate. Vimy Ridge with Ecole & La Folie Farm are being pulverized by our artillery. I go to the Crater also Subway & to 11 Bde. Area.
In afternoon there are many air flights. Both sides patrol their own lines, then dart forward when opportunity offers & do battle. Enemy has much faster machines than ours. One of our battle ‘planes go over his lines decoyed by an enemy ‘plane painted red. He is set upon by 3 others & forced to descend. His machine bursts into flames 500 feet up & lands in German line N. of Vimy.
