March 1915, Wittgenstein is sent to the Russian front to man an artillery night observation post. He sees combat, suffering, death. Diary prayers begin again.

October 1915, Ludwig begins to recast as a book his work, his thinking on logic of the past three years.

July 1918, after many battles, after two citations for bravery under fire, Leutnant Ludwig Wittgenstein turns up in a Salzburg railway station, disoriented, distraught and suicidal. Uncle Paul coaxes him to his home in Hallein.

August, 1918. In Hallein Ludwig finishes the manuscript he has rewritten so many times in the past three years, and dedicates it to: David Pinsent.
