""Their first step", Pavelic continues, "after the end of the war in 1918 was to immediately contact Dr. Horvat (Aleksandar, the president of Croatian Party of Rights - Z.K.). , these officers met with me."
You're welcome.
"Their first step", Pavelic continues, "after the end of the war in 1918 was to immediately contact Dr. Horvat (Aleksandar, the president of Croatian Party of Rights - Z.K.). Owing to the fact that Dr. Horvat had already resigned because of well known events in October 1918, these officers met with me."
So unless Horvat had a time machine and was able to travel into the future to 1918 to see what had happened, he could not have possibly resigned in 1917 because of the events of 1918.
