KYIV – The Ukrainian marine infantryman endured nine months of physical and psychological torture as a Russian prisoner of war, but was allotted only three months of rest and rehabilitation before being ordered back to his unit.

The infantryman, who asked to be identified only by his call sign Smiley, returned to duty willingly. But it was only when he underwent intensive combat training in the following weeks that the depth and range of his injuries, both psychological and physical, began to surface.

“I started having flashbacks and nightmares,” he said. “I would only sleep for two hours and wake up with my sleeping bag soaking wet.” He was diagnosed with post-traumatic stress disorder and referred for psychological care, and is still receiving treatment.

Ukraine is just beginning to understand the lasting effects of the traumas that its prisoners of war experienced in Russian captivity, but it has been failing to treat them properly and returning them to duty too early, say former prisoners, officials and psychologists familiar with individual cases.

Nearly 3,000 Ukrainian prisoners of war have been released from Russia in prisoner exchanges since the 2022 invasion began. More than 10,000 remain in Russian custody, some of whom have endured two years of conditions that a United Nations expert described as horrific.

The Ukrainian government’s rehabilitation programme, which has usually involved two months in a sanitarium and a month at home, is inadequate, critics say, and the traumas suffered by Ukrainian prisoners are growing with the length and severity of the abuse they are being subjected to as the war drags on.

Russia’s torture of prisoners of war has been well documented by the UN, with former inmates speaking of relentless beatings, electric shocks, rape, sexual violence and mock executions, so much so that one expert described it as a systematic, state-endorsed policy. Many detainees have also reported lingering symptoms such as blackouts and fainting spells stemming from repeated blows to the head that were severe enough to cause concussions.

Ukraine’s prosecutor-general Andriy Kostin said in September that “about 90 per cent of Ukrainian prisoners of war have been subjected to torture, rape, threats of sexual violence or other forms of ill-treatment”.

The Russian military did not answer a request for comment on the allegations of mistreatment of Ukrainian prisoners of war.

Ukrainian prosecutors have identified 3,000 former military and civilian prisoners who can serve as witnesses for a case they are building for the Ukrainian courts to charge Russian individuals and officials with mistreatment of prisoners. The prosecutors encouraged two of the former prisoners to speak to The New York Times.

One of them was Smiley, 22, who was captured at the beginning of the war when the Russian navy seized Ukrainian positions on Snake Island in the Black Sea. He spoke a year after his release, saying he hoped that shedding light on the conditions of Russian prisons would help not only his own rehabilitation, but also the thousands of prisoners of war still in captivity.

“My sister persuaded me to give my first interview,” he said. “‘You need to tell,’ she said. Maybe if we speak, it will help the treatment of our guys.”

A second Ukrainian serviceman made available by the prosecutors gave a lengthy interview but declined to give his name or call sign, because of the stigma surrounding the abuses he suffered.

The serviceman, 36, said he was taken prisoner along with several thousand soldiers and marines after a long siege at the Azovstal Iron and Steel Works in Mariupol in May 2022. He spent nine months in Russian captivity before being released in a prisoner exchange in early 2023.

He spent most of his time in three detention facilities in the Russian towns of Taganrog, Kamensk-Shakhtinsky and Kursk. He returned critically underweight and with an injured spine and, like many others, blackouts, dizziness and ringing in the ears from frequent beatings on the head.

“I am not fainting any longer,” the serviceman said, “but I have difficulties with my back and concussion, and a squeezing all the time of the area around my heart.” Despite his injuries, he was ordered to return to light duty as a guard after only two months’ rest in a sanitarium.

Smiley said much of the violence was of a sexual nature. One prison unit repeatedly struck prisoners all over their bodies, including on the genitals, with batons that gave electric shocks, he said.

On another occasion, he said, a cellmate was repeatedly kicked in the genitals during roll call, where the prisoners were lined up with their legs spread, facing a wall in a corridor. Smiley was permanently injured with an untreated broken pelvis from a truncheon blow, and could not bend or lie down without assistance for two weeks.

The International Committee of the Red Cross, which has very limited access to prisoners of war held in Russia, was not permitted to visit him during his nine months of imprisonment, he added.

The second serviceman said he was forced to strip and place his genitals on a stool as his interrogators hit them with a ruler and lay a knife on them, threatening to castrate him.

Interrogators put him through a mock execution, firing a volley of gunfire beside him while he was blindfolded. They threatened him with rape, the serviceman said, making him choose what they should use – a mop handle or the leg of a chair. “Do you want to do it yourself or do you want us to help you?” they taunted him.

He said he was never actually penetrated, but others were raped. “After that, you cannot walk normally,” he said. “You suffer for weeks. Other guys had the same treatment.

“I think they had such an order to break us psychologically and physically so that we would not want anything else in life,” he said, adding that there were suicides in the Taganrog jail.

“You could hear the screams all day,” the serviceman said. “Impossible screams.” Sometimes during a lull, the prisoners could hear the voices of children playing outside, he said.

The ordeal for the former prisoners is by no means over once they are back home.

“The most difficult thing is having too many people around,” the serviceman said. “Everyone is peacefully walking in the park and you are still afraid that someone is listening, or that you might get shoved or say the wrong thing.” NYTIMES
