The line of cover is an extemporized parallel, the men are crowded into
uncomfortable positions, several units are mixed. These are conditions
likely to create disorder, the worst enemy of the assault. Think well as
long as you are under cover because amid the bullets you march straight
ahead without thinking. Transmit simple indications from man to man and
orders to the chiefs of section by note.
Have all cease firing except the best shots; firing unnerves and
distracts the noncommissioned officers and soldiers. On the contrary,
silence is at once a mark of order; it impresses the men who collect
themselves and make the appeal for a supreme resolution to their inner
selves.
