In what year was the campaign of Alexander the Great in Asia Minor before the battle of Issus?

In 334 BC, Alexander the Great began his famous march to the East, which changed the world. Before the battle on the Issa River, another significant event took place – the defeat of the Persian satraps on the Granicus near the legendary Troy. The unsuccessful position of the Persian infantry on the slopes of the hills led to the defeat and flight of the cavalry. With the defeat at the Hellespont, the satrapies of Asia Minor began to fall away from the Persian state one after another, and the entire region came under the control of the Macedonians. Only Miletus and Halicarnassus were taken by storm.
