Here's a bit more info:
The daylight bombing of Schaffhausen on 1 April 1944 by the United States Army Air Forces (USAAF) was the most serious of all incidents between the Allies and Switzerland. Approximately 50 B-24 Liberators of a larger force misidentified Schaffhausen as their target Ludwigshafen am Rhein near Mannheim (about 235 km north of Schaffhausen), and dropped sixty tons of bombs on the town. Although an air raid alarm sounded in Schaffhausen, air raid sirens had been set off so many times without any attack that the locals felt safe, and many failed to take cover. A total of 40 people were killed and about 270 injured, and large parts of the town were destroyed.[9] At the insistence of the Swiss government for an explanation, Allied investigations into the incident found that bad weather broke up the American formation over France, and that high winds that nearly doubled the ground speed of the bombers confused the navigators. (Two other widely scattered cities in Germany and France were also mistakenly bombed during the same mission.) As Schaffhausen is situated on the right bank (north side) of the Rhine river, it was apparently assumed to be the German city. By October 1944, US$4,000,000 had been paid in restitution.

Yep....... my IWC GST is a great watch and a keeper.
