English: "Oprop!" (Outcry! / Proclamation!)

The 9th of April 1940 was a shitty day for the Danish Kingdom. This is the backside of a leaflet dropped from a german aircraft bomber on the day of invasion. The government capitulated later the same day... For many years after, the Danish defense strategy was based on the phrase "Never again an April 9th!"

This document, written in a peculiar Google Translate-ish dano-norwegian is probably the single most known piece of paper in the Denmark. It's from my fathers collection, and he was 16 at the end of the war. Had it lasted a year or two longer, it is likely he would have been subject to enforced conscription in the german army (SS), since the danish army had been dissolved in 1943.
