What did Snake Island's handover reveal on 30 June 2022?

What did Russia's departure from Snake Island mean on 30 June 2022? Moscow announced that it had withdrawn from the Black Sea island as a "gesture of goodwill". Ukraine said something different: that its forces drove the Russians out after a massive artillery assault.

The two accounts matter because the occupation was long. Russian naval forces attacked the island on 24 February 2022, the first day of the full-scale invasion, and captured it along with its garrison. The occupation that followed lasted 126 days and ended on 30 June.

Two stories, one island

Russia framed the withdrawal as a voluntary act. Ukraine presented it as the result of military pressure. The island itself, small and strategically located in the Black Sea, was back out of Russian hands either way, and that outcome was the one point on which both sides agreed.

Pressure elsewhere in the south

The preceding day, 29 June, showed a different picture in occupied territory. Russian-appointed military-civilian authorities in Kherson announced a referendum on whether the region should join Russia. On the same day, Russian security forces detained Ihor Kolykhaiev, the de jure mayor of Kherson, after Russian-installed officials said he had refused to follow orders.

Taken together, these steps showed Russia tightening its political hold on Kherson Oblast even as it gave up a position at sea.

The alliance backdrop

On 29 June, at the NATO summit in Madrid, U.S. President Joe Biden announced a new permanent U.S. military base in Poland, the 5th Army's Headquarters. It had maintained a forward command post in Poznań since the previous year, and Poland's government had long requested such a base.

The days around 30 June therefore combined a contested military result in the Black Sea, an announced referendum and a mayor's detention in Kherson, and a decision on a permanent U.S. presence in Poland.
