100 Years on – Isonzo

Italy signed a treaty with the Entente nations in early 1915, promising to open a new front against the Austro-Hungarians in exchange for territory taken from Vienna.  The Italians chose as their target the area that is now known as Slovenia, and staged a series of bitterly fought frontal assaults against the Austrians at the Isonzo River, beginning on June 23, 1915.

The fighting along the Isonzo was brutal, costly, and ultimately pointless.  Twelve Battles of the Isonzo occurred by the end of the war, causing hundreds of thousands of deaths on both sides in exchange for a static front that never moved more than a few meters one way or another.

Quote of the Day

It is our part with the help of Divine holiness to defend by armed strength the holy Church of Christ everywhere . . . it is your part, most holy Father, to help our armies with your hands lifted up to God like Moses, so that by your intercession and by the leadership and gift of God the Christian people may everywhere and always have the victory over the enemies of the Holy Name.

— Charlemagne, in a letter to Pope Leo III, 796 AD
