result of this and other failures, new artillery techniques were developed.
One of the first to be trialled successfully was the concept of the
'creeping barrage'. Rather than having a long bombardment for days
before the attack, under this scheme the bombardment would start shortly
before the order to advance. The bombardment would then move forward
just in front of the advancing troops, normally at a rate of approximately
50 metres per minute. Although this method required very careful planning
it had a number of advantages. It prevented the enemy from having
too much notice of an attack and was able to provide cover for the
advancing troops. The creeping barrage was successful and was used
in many more campaigns. It was particularly useful when combined with
the use of tanks and aircraft.
barrage was not the only development in artillery techniques. Use
also started to be made of various methods of hitting specific targets
more accurately. This included the use of aerial reconnaissance shots
to pinpoint enemy gun positions, sound ranging (using the sound of
the enemy gunfire to guess their position) and 'flash-spotting' (using
the flash from the gun muzzles of the enemy to locate enemy positions).
These counter-battery barrages and attacks were much more successful
and certainly helped the Allies in their campaign.
