Casualties
The Ottoman 3rd Army started with 118,000 fighting men. It was reduced to 42,000 effective soldiers in January 1915. There are conflicting figures for Ottoman casualties. Sources do not agree on what sould be included in the final sum. The Turkish official history states 32,000 KIA, 15,000 died of sickness, 7,000 prisoners, 10,000 wounded, for some 50,000 total casualties. The casualties of the conflict escalated beyond the end of the active warfare period as the most immediate problem confronting the 3rd Army became the typhus epidemic. TAF presents a figure of 60,000 casualties throughout the period of the operation. Russians took 7,000 POWs including 200 officers. These prisoners were kept under confinement for the next three years in the small town of Varnavino east of Moscow on the Vetluga River. After the final days of the Czarist empire, these soldiers had a chance to return to the ailing Ottoman Empire.
Russian losses were 16,000 killed in action and 12,000 died of sickness, mostly due to frostbite. TAF sources report around 30,000 fatalities without giving details on the breakdown of this number.
