On 19 August 2014, Semenchenko was wounded by shrapnel when his forces were hit by mortar fire before entering the town of Ilovaysk, 18 kilometers east of Donetsk. He underwent an emergency surgery and recovered slowly. He was later awarded the Order of Bohdan Khmelnytsky by the Minister of Internal Affairs Arsen Avakov. During 2014 he was always photographed while wearing a balaklava. Removing it on 1 September 2014, he stated, "I was never afraid, I was worried about my family; they are now safe and I'm not afraid."
