Some of Mr. Malinowski’s other projects have also aligned with Kremlin interests. Last year, he organized the reburial of the remains of French soldiers who died during the Crimean War of 1853 to 1856. The burial took place in Crimea, a former Ukrainian peninsula that Russia annexed in 2014, despite the opposition of most Western powers.
“Our projects,” said Ms. Peskova, “are cultural, historical, diplomatic and political.”
She added, “We look like Putin’s puppets, but that’s not on purpose.”
By early 2020, General Gudin’s repatriation seemed to be on track. The coronavirus pandemic was expected to delay plans for several months, but Mr. Peskov told several news outlets that the Kremlin would respond positively to a French repatriation request.
The request never came.
In August 2020, Aleksei A. Navalny, Mr. Putin’s most prominent opponent, was poisoned in an operation later revealed to be orchestrated by the Kremlin.
Mr. Macron’s enthusiasm for a rapprochement with Mr. Putin waned significantly. Plans for a joint presidential ceremony were postponed, diplomatic exchanges ceased and communications with Mr. Malinowski dried up.
“We entered a phase of total freezing,” said Christian Bourdeille, the president of Paris Napoléon 2021, an organization that helped plan the ceremony.
“Gudin, really, was the word to avoid,” he added. “Because everybody knew it was an extremely sensitive issue.”
