Take the following as truth: After the disaster at Caporetto, the planned Austro-German 1917 advance across the Veneto plain was held until the Italian counterattack of October November 1918 permitted a triumphant entry into Trento and Trieste.
Then the following statement: "Trento and Trieste was completely cut off, and the Austro-German advance in 1917 was stopped." is true, false, or inconclusive?
