During both Balkan Wars of 1912 and 1913, Alexakis’ troops moved swiftly and brought key battles to successful conclusions. A few amongst the many are: the Battle of Arnaia on 2 November 1912, Ierissos and the seize of Mount Athos from the Turks before the arrival of the Bulgarians, the Battle of Kilkis–Lachanas in June 1913 and the fight over Height 1378 in July 1913. These strategic victories came with heavy casualties on both sides; Greece: 8652 killed and wounded; Bulgaria: 7000 killed and wounded and 2500 captured. During these battles Alexakis was injured twice, and on 12 July 1913, seriously in the heart. But after these decisive battles, Bulgaria was driven from Macedonia.
