From the "fog of war" on the fields between Ukraine and Russia, images and rumors emerge about the tragic fate of dozens of North Korean soldiers sent to the front by Kim Jong-un.
According to GUR, Kiev's military intelligence, the North Korean contingent fought the first battle on December 14 and 15 and suffered "significant losses" at Kursk.
In that Russian region partially occupied by Ukrainians last August, Moscow's forces are carrying out a bloody counteroffensive.
And in the attack on several Kursk villages around which the Ukrainians had created minefields, the Pyongyang contingent would have lost at least 30 men dead or missing: a Ukrainian drone filmed 23 corpses lined up in the snow, which according to GRU analysis are North Korean.
From Washington, the Pentagon confirms that Pyongyang's units are on the front lines and have begun fighting after being trained for several weeks to operate within Russian units.
It also seems to the Americans that Kim's legion, which numbers about 11,000 men, suffered its first serious losses last weekend.
Ukrainian President Volodymyr Zelensky claims that to erase traces of North Korea's involvement, the Russians are "burning the faces of the fallen."
In a social media post, Zelensky included a video in which we see soldiers with Asian features positioned among trees and then flames engulfing the head of a corpse lying on the ground.
"A demonstration of Russian contempt for all forms of humanity in this war," Zelensky says.
"There is no single reason why North Koreans should fight and die for Putin. And even after they do, Russia has only humiliation in store for them. This madness must stop, with a credible and lasting peace."
Various information is circulating about the clashes of December 14 and 15 in Kursk, some from Russian bloggers, others from Ukrainians.
According to Kiev, Kim's soldiers use tactics from 70 years ago, attacking in waves, but they fight well.
“They continued to advance, ignoring losses from our precision fire and artillery fire,” wrote a military website in Kiev. North Korean special forces reportedly retook the ruins of the village of Plekhovo; Ukrainian intelligence says North Korean platoons were embedded in battalions of Russian elite forces and that suicide drones and artillery were used to repel them.
About 200 people died in the battle around the villages of Plekhovo, Vorobzha and Martynovka, of whom 30 were North Koreans.
In several videos taken by drones and published on Telegram from Kiev, the faces of soldiers can be seen looking up, stunned by the threat.
Then bomb explosions and finally the 23 corpses were lined up on the frozen ground.
"We observed with our drones that after the clash a North Korean patrol arrived on the ground, grouped the corpses and covered their faces," the Kiev military said.
The soldiers sent by Pyongyang, in the opinion of Ukrainian veterans, would fight bravely, but would be unprepared for this war fought even with drones that dominate the movements on the battlefield from the sky.
The Khorne Group of the Ukrainian 116th Mechanized Brigade, which specializes in “target acquisition,” claims that the North Koreans fooled themselves into thinking they could hide from drones by wearing white helmets in the snow.
However, the Ukrainians noticed that the North Koreans are learning survival tactics.
"Sometimes they operate in twos or threes, targeting our drones and managing to shoot them down with fire from their individual weapons," an official wrote on Telegram, concluding that "this reaction shows that Pyongyang has sent special forces that perform relatively well in our difficult theater of operations."
In addition to receiving Vladimir Putin's gratitude, it is likely that Kim sent his contingent of fighters precisely to forge them in a real war: an experience that could be useful in the future at the 38th parallel that divides the Korean peninsula in two.
Ukrainian sources claim that the action of the Russian-Korean assault forces was hampered by communication difficulties between the two allied contingents, primarily the rudimentary knowledge of Russian by the Pyongyang soldiers.
During the short period of “acclimatization” in the rear, between October and November, the North Koreans were taught 100 military language expressions in Russian, including “ready” and “fire.”
The language barrier would have caused at least one serious incident: the North Koreans would have accidentally fired on the Chechen Akhmat battalion, which is fighting alongside the Russians, killing eight men.
