Putin’s forces suffer biggest monthly losses of 2026 so far

According to an October 1 update from Ukraine’s General Staff, Russian forces suffered 46,230 personnel losses during September alone.

It is the highest monthly total recorded anywhere in 2026.

The autumn total easily eclipsed previous records set during the summer, when official logs registered 42,860 Russian casualties in July and another 42,020 in August.

By comparison, monthly figures had stayed much lower earlier in the year, hovering at 31,710 in January and 26,090 in February before steadily climbing throughout the spring.

Between January and September, monthly losses expanded by 14,520 troops. That represents a steep 45.8 per cent jump in casualties over nine months.

Deadliest single day

Daily losses spiked too.

UK Defence Intelligence highlighted an extraordinarily intense 24-hour period late in the month.

Citing data from Ukraine’s General Staff for September 28, the UK agency reported that Russian forces suffered 2,090 casualties killed or wounded in a single day.

That single-day count marks the highest reported loss for Russian troops since the full-scale invasion began in February 2022. Only three other days throughout the entire war, all occurring in 2024, have seen daily casualties exceed 2,000.

September also saw the fourth-highest daily casualty count of the entire conflict when Ukrainian forces recorded 1,960 personnel killed or wounded on September 16.

The growing cost

These latest casualty spikes add to a staggering total accumulated over more than two years of heavy warfare.

Data released by Ukraine’s General Staff on September 9 showed that total Russian casualties had officially passed 1.5 million troops killed or wounded since February 2022.

The human toll keeps rising. Frontline fighting shows no sign of slowing down as both armies brace for cold weather.
