Since the Italians joined the war in 1915 they have launched nine offensives against the Austro-Hungarians on the Isonzo line. All have failed, apart perhaps from the Sixth Battle, which saw Italy capture frontline town of Gorizia.
Now shelling begins for the tenth offensive. The Italians have built up their artillery, doubling the number of medium and heavy guns available a year ago. They now have 3,000 guns at the Isonzo, a smaller concentration than would be seen on the Western Front, with less shells for them to fire, but this is still capable of blasting the Austro-Hungarians with an intensity never before seen on this front. Cadorna hopes that this time after a short artillery bombardment the infantry will be able to smash through the enemy and achieve the breakthrough that has long eluded him.
