What 6 September 2023 revealed about the war

What did a single day reveal about the state of the war? On 6 September 2023, the Russian invasion of Ukraine moved on several tracks at once: Western military aid, battlefield losses, a mass-casualty strike on civilians, spillover concerns in Romania and diplomacy over Black Sea grain.

Aid, and the cost of using it

The United States announced a $175 million aid package for Ukraine on 6 September 2023. It included depleted uranium ammunition for the first time, intended for use with Abrams tanks.

The same day, British Defence Secretary Grant Shapps confirmed reports from Russian officials that a Challenger 2 tank had been destroyed in Ukraine. It was the first loss of the model on the battlefield. Taken together, the two announcements showed Western armour and its supplies moving into the fight, and one of those systems suffering a loss.

Kostiantynivka

The gravest event of the day was a missile strike on a marketplace in Kostiantynivka, Donetsk Oblast. At least 15 people were killed and 30 others injured. Kyiv blamed Russia for the attack, and Russia denied involvement.

An investigation by the New York Times found evidence suggesting that a Ukrainian 9M38 missile, fired by a mobile Buk antiaircraft vehicle, was responsible. That finding sits against Kyiv's attribution. According to the later-written background, a Security Service of Ukraine spokesman said the official investigation was continuing and that, for the time being, it believed the weapon was an S-300 missile launched by Russian forces. The background also gives a figure of at least 32 wounded and notes that the dead included a child and a couple in their 50s who had been selling flowers at the market.

The competing accounts matter because the strike was an attack on civilians in a town in Donetsk Oblast, and responsibility was contested from the first day. The reporting available on 6 September 2023 did not settle the question.

Spillover and the Black Sea

Romania's Ministry of National Defence confirmed on 6 September 2023 that debris from a Russian drone had been found on Romanian territory in Tulcea County. Romania denied claims that drones launched by Russia had exploded on its territory. The distinction was between debris found and an explosion claimed, and Bucharest drew it explicitly.

The Black Sea was also the setting for the day's diplomacy. Russian President Vladimir Putin and Turkish President Recep Tayyip Erdoğan held talks in Sochi, Russia, on reviving the Black Sea Grain Initiative, which would enable the passage of grain across the sea.

The background describes the initiative as an agreement between Russia, Ukraine, Turkey and the United Nations. It was signed in Istanbul on 22 July 2022 for 120 days, and a joint coordination and inspection centre was set up in Turkey with the UN as secretariat. It was created after the invasion halted maritime grain shipments from Ukraine, a major exporter, which pushed up world food prices and raised the threat of famine in lower-income countries. Russia faced accusations of weaponising food supplies. Against that background, the Sochi talks concerned a mechanism that had previously addressed a food crisis.

The Black Sea was a military theatre as well. On 5 September 2023, Russia's defence ministry said it had repelled a Ukrainian aerial drone attack over the Black Sea. It also said it had destroyed four Ukrainian military boats carrying troops towards Cape Tarkhankut on the Crimean coast. Those were Russian claims, as reported at the time.

Drones, defectors and recruits

Russia's defence ministry also said on 5 September 2023 that it had shot down three Ukrainian drones, over Istra, Moscow, and over the Kaluga and Tver regions near Moscow.

Two smaller items completed the picture. On 6 September 2023, Russian pilot Maxim Kuzminov, who had defected to Ukraine with a Mi-8 helicopter, received a $500,000 reward. On 5 September 2023, Cuba's foreign ministry said criminal proceedings had been initiated against a recruiting group seeking mainly to enlist Cuban citizens living in Russia to fight in Ukraine. It noted that mercenary activity is prohibited in Cuba and reiterated that Cuba was not part of the war.

What the day shows

The 6 September 2023 reporting shows a war that was military, civilian, diplomatic and informational at once. Western equipment was arriving, and the Challenger 2 loss showed it was exposed to risk. A deadly strike on a market produced contested attribution. A drone fragment in Romania produced a careful official distinction. And talks in Sochi centred on grain, the commodity whose disrupted shipping had shaped the war's wider economic effects.
