FACT CHECK: Zelensky is right about Lyman, but his 10,660 Russian casualties remain unverifiable

Every loss on video

A two-part answer

Volodymyr Zelensky said on September 27 that the Ukrainian army had put 10,660 Russian soldiers out of action in one week. On Lyman, he is right. On the number, no one can say.

He adds a detail. Every loss is backed by video, according to Ukrinform.

One video, you watch. Thousands, you count. These do not come with the message.

This text checks two sentences. Not a war. Two sentences, posted on a Sunday.

The operator’s gray rectangle

On a drone operator’s screen, the war fits in a gray rectangle. A dot moves. Then it stops moving.

There is the hum of the computer fan. There are numb fingers on the controller. There is the picture jumping when the signal weakens.

In that picture, a wounded man sometimes looks like a dead one. A dead man, sometimes, like a wounded one who will be evacuated.

Kyiv’s number adds up those images. Thousands of them. Each one, it says, verified.

Hence the phrase Kyiv chose. Out of action. Dead or wounded, with no breakdown.

A video shows a body, not a total.

The September 27 message

On Telegram, after Drapatyi

The message was posted on Telegram on Sunday, September 27. Ukrinform relayed it at 3:21 p.m.

Zelensky says he received the report of the commander in chief of the armed forces, Mykhailo Drapatyi.

This week, “our units neutralized 10,660 Russian troops,” dead and wounded, he writes. Across all active sectors of the front.

The word neutralized is the army’s. It covers the dead and the wounded without separating them.

Vivaldi and the air assault troops

He cites Operation Vivaldi, in the Lyman sector of Donetsk. And another active defense operation led by the air assault troops.

He thanks the 3rd Army Corps and the 68th Oleksa Dovbush Brigade.

The operation was made public only on September 15, the Kyiv Independent recalls. Russian Telegram channels and open-source researchers had been tracking Ukrainian attacks in the area since late spring.

Twelve days with a name. Months of fighting.

The heaviest fighting, he says, is toward Pokrovsk, Kostiantynivka and Lyman.

No square kilometers are announced. No details on gains, the Kyiv Independent notes.

Two claims, and neither comes with its proof.

Two answers, not one

Supported, then unverifiable

My answer fits in two lines.

On Lyman: supported. The Institute for the Study of War, in Washington, has been documenting Ukrainian gains north of the town for weeks.

On the 10,660: unverifiable. No independent counter publishes a weekly tally of Russian losses.

The map confirms the direction, not the count.

9,440 on the other side

While Kyiv announces its 10,660, Moscow publishes its mirror image.

On September 28, the Russian agency TASS relays Andrei Marochko, presented as a military expert. According to him, Ukrainian forces lost about 9,440 men, dead and wounded, in one week, including what he calls mercenaries. He says he analyzed Russian Defense Ministry data.

Two belligerents. Two numbers close to 10,000. Two weeks that almost overlap.

Marochko adds about 6,000 Ukrainian drones destroyed, 49 artillery pieces and more than 600 vehicles. His total would be 115 higher than the previous week’s.

Everything is precise. Nothing is shown.

Neither one publishes its own losses in the same message.

Two accountants. No auditor.

Each camp counts the other camp’s losses.

10,980 at the General Staff

Seven bulletins added up

First check. Ukraine’s General Staff publishes its tally of Russian losses every morning.

On September 21, it showed about 1,519,650 Russian troops out of action since February 2022, according to Ukrinform. On the 27th, 1,528,970, including 1,690 in 24 hours.

Add the 1,660 from the September 21 bulletin. The seven bulletins published from the 21st to the 27th total 10,980. That is my own arithmetic.

Drapatyi says 10,660. The gap is 320. Less than 3%.

The bulletin does not say how it is compiled. The agency relaying it does not explain either.

A running total that climbs every morning. That is what a running total does.

Same house, same source

This is not confirmation. Both numbers come from the Ukrainian army, on two calendars.

They are consistent with each other. They rest on nothing external.

And the wounded who die the next day, which column do they go in?

The tally does not say.

Kyiv cross-checks against Kyiv, and that is all.

No independent counter

Mediazona’s warning

The Kyiv Independent puts it in one line. Moscow does not regularly publish its losses, and the number could not be independently verified.

Mediazona, an independent Russian outlet, counts Russian dead by name. Its list was updated on September 21.

The outlet warns that data for recent months are the most incomplete and will change a great deal.

In other words, the week of September 21 to 27 will not be counted in names for months.

Mediazona counts only the dead it can name. That is a floor. Not a total.

A week too short for names

And yet Kyiv’s number is not absurd. On September 15, the General Staff claimed more than 300,000 Russians dead or wounded since the start of 2026, the Kyiv Independent recalls.

Three hundred thousand in a little over 36 weeks works out to a little over 8,000 a week. My arithmetic again.

A week at 10,660 would therefore be heavier than average. Not off the scale.

Plausible. Not proven.

No one counts by the week except the belligerents.

125 square kilometers

What the ISW saw

Second check: the map. Here, video changes roles.

The ISW works from geolocated footage. It does not count the dead. It places positions.

On September 22, the institute wrote that Ukrainian forces had liberated at least 125 square kilometers north of Lyman during Operation Vivaldi.

It sees tactics that allowed them, at the tactical level, to break out of positional warfare in places.

One square kilometer is 100 hectares of fields, hedgerows and mined woods. One hundred twenty-five times over.

On the 24th, the 3rd Corps said it had cleared 30 kilometers of roads toward Shandryholove in two nights, using ground robots, according to the ISW.

Drobycheve, Derylove, Shandryholove

The villages have names. Drobycheve, Derylove, Shandryholove, northwest of Lyman.

On September 20, the 3rd Army Corps announced new gains. Forty more square kilometers, according to the Kyiv Independent. Fifty for the whole second phase, with 800 Russian troops eliminated, according to the ISW’s account.

Two relays, two areas. Perhaps an increment and a total. The message does not allow a decision.

Eight hundred for one phase. Ten thousand six hundred sixty for one week, across the whole front. The two numbers do not measure the same thing.

The maps themselves diverge at the margins. From August 25 to September 22, Russia gained a net 37 square miles according to DeepState data compiled by Russia Matters. According to ISW data, it lost one.

Two maps. Four weeks. Two opposite signs.

Ground can be geolocated. The wounded cannot.

The Zherebets bank

A retreat told from the Russian side

Third check. What the other camp says when it talks among its own.

As early as September 22, a source in the Russian forces said the command was sending reserves toward Lyman to hold the Zherebets line, the ISW writes.

No one sends reserves where everything is going well.

A Russian source talking about a retreat is rare. Several in the same week make a trend.

A Russian source, on September 26, reported a withdrawal from south of Lyman to avoid encirclement, according to the ISW. A Russian source, on the 27th, described a retreat under fire across the Zherebets River, hard to hold.

According to that source, Russian forces now hold only isolated positions near Ivanivka and Zarichne, northeast of Lyman, the ISW reported on September 27.

The culture of lying

On the 25th, a Kremlin-aligned milblogger wrote that the culture of lying in the Russian army had made the Ukrainian success easier, the ISW reports. A Ukrainian commander adds that those inaccurate reports kept the Russian command from seeing Vivaldi coming.

When the other camp confirms your advance, half the work is done.

And yet, for September 26 and 27, the ISW reports no new confirmed Ukrainian advance in that sector.

The recent advances it confirms are elsewhere. East of Sloviansk. In Chasiv Yar. Toward Oleksandrivka.

The sector is not quiet for all that. Ukrainian counterattacks continue, the institute wrote on the 27th.

The direction is confirmed. The week has no measure.

When the other camp falls back, its own voices tell the story.

Sviatohirsk, 20 kilometers back

The Russian ministry’s version

Moscow, officially, tells a different story.

On September 19, the Russian Defense Ministry claimed to be clearing small groups of Ukrainian infantry in Sviatohirsk and Lyman, the ISW reports.

A Russian milblogger contradicted it. Sviatohirsk is at least 20 kilometers from the front, he wrote, and Russian forces do not control Lyman.

Putin’s September 1

Putin had claimed the capture of Sviatohirsk on September 1.

On September 1, a town taken. On the 19th, a town to be cleared. The next day, in the ISW’s account, a town 20 kilometers from the front.

Three dates. Three versions. One town.

On the 27th, the ISW also noted that the ministry is reusing footage to announce captures in the Kharkiv region. The same images, on the 21st and then the 26th, for different villages.

It is not Kyiv writing this. It is an institute comparing the videos.

The same day, the ministry also claimed Khrypuny, a village in the Kharkiv region. The ISW has confirmed no Russian advance there.

Moscow recycles its videos. Kyiv keeps its own.

The number that suits Kyiv

Higher than Western estimates

This has to be said too, and it is what costs me. This number serves Kyiv.

I write it because the other camp would write it first.

Russia Matters, a site that compiles estimates, cites Western officials interviewed by The Telegraph this month: about 1.4 million Russian casualties, including 500,000 dead.

Ukraine’s General Staff counts 1,528,970. About 130,000 more.

Two Ukrainian numbers don’t match either. 10,660 on one side, 10,980 on the other.

A CSIS report, in Washington, put the figure in July at about 1.4 million Russians dead, wounded or missing through June 2026, according to the same compilation.

Kyiv’s total runs ahead. Not by much. But ahead.

A Sunday, after the UN

And the tally lands on a Sunday, at the end of a week of diplomacy in New York, where Zelensky met Donald Trump on September 22.

It reassures the soldiers. It speaks to the capitals. Moscow publishes its own the next day.

And yet I publish it as it is, with its label. It is true that it suits Kyiv. That does not make it false. It makes it unusable as proof.

Unverifiable does not mean false, but it is not proof.

Ten thousand six hundred sixty

A small town every week

Ten thousand six hundred sixty. That is a small town.

One week.

Seven days. Not one more.

The number does not say how many are dead and how many wounded. A wounded man is a leg, an eye, a hand. A dead man is an empty chair in a Russian region no bulletin will ever name.

These men were sent by a decision of the Kremlin. They are not the ones this text accuses.

How many will be back at the front in a month? The tally does not know.

Exhausted and hungry, near Lyman

On September 23, a Ukrainian officer said he had found exhausted, hungry Russian soldiers while clearing positions northwest of Lyman, according to the ISW.

The army that sent them publishes 9,440 Ukrainians out of action. It does not publish its own.

Since February 2022, Ukraine’s General Staff counts more than a million and a half. The number no longer fits in anyone’s head.

It fits in kitchens where a place is still set for no one.

Out of action is still a man, not a unit.

What a Sunday tally is for

A message before a measure

Here is my reading.

It is not an independent measure: none exists by the week. It is not an invention either: the General Staff arrives at 10,980. It is not a calendar coincidence: it lands on a Sunday, with the week’s tally. It is not unique to Kyiv: Moscow publishes its 9,440 the next day. And finally, it is not proof.

It is a message.

Useful. Not verifiable.

Three audiences

It tells the soldiers their week counted. It tells the capitals the army is holding. It tells the Russian generals that Vivaldi goes on.

The proof lies elsewhere. In a geolocated video that places a position on a map.

That kind of video, the ISW has seen. The videos behind the 10,660 have not been made public.

Same object. Two uses.

A tally reassures. A map proves.

What Moscow does not publish

No Russian total

The heaviest silence of the week comes from Moscow.

The Russian ministry publishes the Ukrainian losses it claims, and an expert relayed by TASS adds them up. It does not regularly publish its own.

So it falls to journalists, at Mediazona, to look for the names one by one and comb through probate registers.

The names, one by one

As of September 21, they had confirmed the deaths of 7,692 officers of the Russian army and other security forces.

Officers alone. Only the names found.

The number is small next to the others. It is the only one that carries names.

Who, in the Kremlin, decided that these dead would have no total?

If Moscow published its losses, half of this text…

Without a Russian total, every Ukrainian number stands alone.

The videos, online or not

What Kyiv could open up

What would change my answer comes down to a few things.

Kyiv would have to make the videos behind its 10,660 available, even in part. Independent analysts would have to be able to geolocate them, as the ISW does for ground. Moscow would have to publish its own losses.

That last condition, I don’t expect.

A blurred, time-stamped, geolocated video would be enough. No one is asking for faces.

It would be asking little. It would be asking for proof.

Zarichne and Yampil to watch

For Lyman, the test is simpler. The next maps will show whether the Russian retreat behind the Zherebets is confirmed.

If geolocated images place Ukrainian positions in Zarichne or Yampil, the answer for the week will move from supported to confirmed.

If not, it will stay what it is. A correct direction, with no measure for seven days.

Publish the videos, and the number becomes proof.

Ten thousand, on trust

A direction, not a measure

I would have liked to write that the number was true. I am on Ukraine’s side, and I don’t hide it. But I cannot verify 10,660, and I won’t pretend to.

Lyman, yes. The count, on trust.

It is a fatigue I know. You want your side to be right about everything. It is right about what matters most.

The rest will wait for the maps.

The next Sunday

Next Sunday, another number will arrive. Moscow will publish its own the day after.

At the next Sunday tally, what will you check first, the number or the map?

The map is slower. It is wrong less often.

Every video placed on it weighs more than a thousand promised.

Lyman shows on the map. The 10,660 are taken on trust.
