Who is Stephen Hubbard? Why did Putin free the 74-year-old US teacher jailed as a Ukraine war ‘mercenary’? Explained

Stephen James Hubbard is a retired American teacher from Big Rapids, Michigan. He had lived in eastern Ukraine for several years before Russia launched its full-scale invasion in February 2022. His case mattered because it involved an elderly American, disputed wartime allegations, and detention by Russia during a major international conflict.

Russian forces detained Hubbard about two months after the invasion while capturing territory in eastern Ukraine. Prosecutors alleged that he had signed a contract with Ukraine’s military and fought alongside its forces. His legal team rejected that account and said he had not taken part in military activity. A Russian court sentenced him in 2024 after closed proceedings.

Hubbard spent nearly two years in detention and received a sentence of almost seven years. President Donald Trump said he asked Vladimir Putin to release him. Putin later pardoned Hubbard on humanitarian grounds, and US envoy Steve Witkoff received him at an airport in St Petersburg before his return to the United States.

A mercenary is generally a person recruited to fight in an armed conflict mainly for private gain, outside the regular armed forces of a party. The label matters because states may prosecute alleged mercenaries under domestic law, and because it can affect how authorities describe a detainee’s status. The article does not establish whether the legal definition was satisfied.

Russian prosecutors alleged that Hubbard signed a contract with the Ukrainian military and fought alongside Kyiv’s forces. Russian forces captured him in eastern Ukraine about two months after the full-scale invasion began. A Russian court later sentenced him to nearly seven years after closed proceedings. Hubbard’s legal team rejected the prosecution’s account.

His lawyer maintained that Hubbard had not participated in military activity. Family messages cited in the article also did not indicate that he had joined Ukraine’s military. The available account therefore contains a direct dispute: Russian prosecutors described him as a mercenary, while his defence denied the conduct behind that accusation.

Hubbard’s age and detention made his case especially striking. He was 74 when Russia released him, and the article describes him as a retired American teacher. His age drew attention because he was held during wartime and accused of taking part in military activity, allegations his legal team rejected.

Russian forces detained Hubbard about two months after the full-scale invasion began in February 2022. He remained in detention for nearly two years. In 2024, a Russian court sentenced him to almost seven years in prison following closed proceedings. The article does not provide an exact detention length in months or an exact sentence in years and months.

Hubbard did not serve the full sentence. Putin later pardoned him, and Russian authorities handed him to Steve Witkoff at Pulkovo Airport in St Petersburg. He then began his journey back to the United States. His release occurred during renewed diplomatic contact between Washington and Moscow over the war.

Hubbard’s pardon came during renewed diplomatic engagement between Washington and Moscow. Russian officials said the American side had raised his release over time, while Kremlin spokesman Dmitry Peskov described Putin’s decision as based on humanitarian considerations. The pardon mattered because it freed an elderly American held during the Russia-Ukraine war.

Donald Trump said he asked Putin to release Hubbard during a phone call the previous week. Trump also said the United States did not have to release anyone in return. During a visit to Russia, US special envoy Steve Witkoff met Putin in St Petersburg for talks that included the war in Ukraine.

Russian foreign policy aide Yuri Ushakov said Putin had pardoned Hubbard. Russian authorities then handed Hubbard to Witkoff at Pulkovo Airport. Witkoff thanked Putin publicly and described the release as humanitarian. The episode linked an individual detention case to wider diplomatic efforts, although the article does not report a broader agreement resulting from it.

The release could help diplomatic efforts by showing that Washington and Moscow can address a humanitarian case during a larger conflict. It gave both sides a concrete outcome while US officials were pressing for an end to the fighting. Such outcomes can keep communication open, especially when broader negotiations remain difficult.

The timing was important. Trump said he had asked Putin to free Hubbard, and Witkoff met Putin in St Petersburg during a visit focused partly on the war. Russia then handed Hubbard to Witkoff without a reciprocal American release, according to Trump. That sequence connected a personal case with high-level diplomatic engagement.

The immediate result was Hubbard’s return journey and a public expression of cooperation. The article does not say the release produced a ceasefire, peace agreement, or change in battlefield conditions. Its forward significance is therefore limited but real: humanitarian decisions may support continued contact, while negotiations over the war remain unresolved.

These features matter because international law places importance on lawful detention, fair proceedings, and the treatment of people captured during armed conflict. A closed trial can restrict public access to evidence and make independent assessment more difficult. Disputed allegations also mean that a conviction should not automatically be treated as an established account of events.

In Hubbard’s case, Russian prosecutors said he had contracted with Ukraine’s military and fought for its forces. His lawyers denied that he had taken part in military activity. A Russian court sentenced him after closed proceedings. The Biden administration reportedly designated Hubbard as wrongfully detained, meaning the United States considered his detention unjustified and sought his release.

That designation was a diplomatic and policy position, not a substitute for a court’s legal findings. The article does not report an international tribunal ruling on Hubbard’s conduct. His pardon ended his imprisonment, but it did not publicly resolve the disputed facts or establish whether Russia’s prosecution complied with international standards.

A presidential pardon is an executive act that removes, reduces, or ends punishment for a person convicted under the authority of that state. In Hubbard’s case, Yuri Ushakov said Putin pardoned him, allowing his release before he completed his nearly seven-year sentence. A pardon does not necessarily mean the underlying allegations were disproved.

A prisoner exchange works differently. It involves two sides transferring detainees under agreed terms, usually with each side releasing someone in return. Trump said the United States did not have to release anyone for Hubbard’s return, so the article describes his release as a pardon rather than an exchange. No reciprocal release was reported.

Consular negotiation is broader. Government officials may seek access, information, fair treatment, or release for a citizen held abroad. It can occur without a pardon and without trading prisoners. The article describes repeated American requests and Trump’s direct appeal to Putin. Those efforts preceded the Russian decision, but the formal act was Putin’s pardon.
