A lethal plume of toxic smoke was blowing towards us from a blaze at a battery manufacturing plant in Kaliningrad.
Troops in the Russian exclave had been ordered to help put the fire out: untrained and under-equipped, they mutinied. Terrified civilians were thronging the borders.
The Kremlin, oblivious to the unfolding humanitarian and environmental catastrophe, blamed the West for sabotage and incitement, and demanded a transit corridor across Lithuania.
However, none of this actually happened.
We (20 retired and serving officials, experts, and others) were in the safety and comfort of the Wargaming Lab at the ISM university in Vilnius, as guests of the Baltic International Security Centre (BISC).
The crisis scenarios were hypothetical; the aim was to explore the dilemmas and trade-offs they created. (You are the Lithuanian government. Do you let the mutineers in? Or leave them to be massacred?)
The games-master provided regular “injects” – new developments – such as ill-written social media posts from US president Donald Trump. He blamed the authorities in “Lithvastonia” for having started the fire in “Kaliningradia”.
An amusing parody, we thought. A few hours later, the real US president published news of his deal with Russian president Vladimir Putin on sanctions-busting diesel imports, then blamed Ukraine for being invaded.
Not so amusing, especially for our Ukrainian participant, a senior military commander there.
As we were leaving (us to safety, him to danger), news broke that Russia is stepping up its assassination attempts in Europe, targeting defence industry bosses (and perhaps Polish politicians). Our scenarios seemed tame in comparison.
