Two days before the wave reached Wrocław, a Gazeta Wyborcza edition reassured readers that the city was not at risk of flooding, perhaps a wet basement at worst. By Saturday, 12 July 1997, the Oder was breaching embankments at Żabia Grobla and Traugutt Street, the river was rising to first-floor windows in the city centre, and roughly forty percent of Wrocław was underwater. Poles call what happened that summer the powódź tysiąclecia, the Flood of the Millennium. Across Poland fifty-six people died and damages reached around 3.5 billion dollars, but the more remarkable number is the one nobody had in any plan: the volunteer sandbag line that materialised, almost overnight, around a city of more than 600,000.

On the night of 11 July, sappers arrived at the village of Łany, just upriver from Wrocław, with explosives prepared to breach the embankment and bleed pressure off the wave before it reached the city. Residents of Łany and neighbour...
