October 23rd, 1915

- Reinforced with divisions drawn from reserve, today the Italian XIV and X Corps of 3rd Army, the northern wing and centre of the army respectively, launch repeated heavy attacks on the Austro-Hungarian line between Mt. San Michelle and Mt. dei sei Busi.  Again and again, Italian infantry rush forward, often uphill, into heavy enemy fire, and when they manage to reach the first trenches they are met by bayonets and grenades.  Despite losses, numerical inferiority, and exhaustion, the Austro-Hungarian defenders, some of whom consist of Landsturm reserves barely accustomed to the intensity of modern combat, are able to hold repulse every Italian attack.

- The British transport Marquette, carrying troops from Egypt to Salonika, is torpedoed and sunk today by the German submarine U35 in the Gulf of Salonika, though most of the soldiers are rescued.

- Lord Hardinge, Viceroy of India, informs Austen Chamberlain, secretary of state of India, today that his military advisors believe that 6th Indian Division, on the Tigris River near Kut-al-Amara, has sufficient strength both to advance to Baghdad and occupy it, and hold the city until the two divisions of Indian Expeditionary Force A arrive in Mesopotamia to reinforce it.  Chamberlain replies later today with authorization to launch 6th Indian Division towards Baghdad, a momentous decision that in time will have dire consequences.
