On June 11, 1941, a second raid took place in Amsterdam as a result of the attacks on buildings occupied by the German Wehrmacht. Jewish cafes and sports clubs were ransacked. 310 young Jewish men were arrested by the Amsterdam police and Ordnungspolizei. Some came from the Jewish working village of Wieringermeer. They were taken to the SD building on Euterpestraat and then to Camp Schoorl. Some were released for health reasons. The rest of the men were sent to Camp Mauthausen on June 26, 1941. The raid was revenge for a bomb attack by the resistance on May 14, 1941 and an attack on the Luftwaffe telephone exchange on June 3, 1941. None of the Jewish men returned from Camp Mauthausen.
One of those men was Adolph Gerson Frohmann(pictured above). He was murdered in Mauthausen on January 16,1942.
The Nazis arrested 310 young Jewish men. Otto Frank was not arrested, but friends and neighbours from the Merwedeplein area, where he had been living for eight years, were. The raid happened a day before Anne Frank’s 12th birthday.
As a precaution, Otto Frank and other men from the square frequently spent the night at the homes of non-Jewish friends or colleagues. In all likelihood, these events prompted Otto Frank to start thinking about a proper hiding place. After attempts to emigrate to the US had failed, he started working on plans to take his family into hiding in the Secret Annex in earnest in the spring of 1942..
There was a stark contrast compared to the raids that had taken place in Amsterdam in February 1941. At that time, the population of Amsterdam and other cities across the Netherlands, had gone on a massive gneral strike in protest against the persecution of the Jews, but in June 1941, the city stayed silent. The Nazis had violently suppressed the February strike, instilling fear in the population. The Amsterdam resistance newspaper Het Parool and other illegal newspapers expressed their abhorrence of the raids of 11 June. They called on people to not cooperate with the Germans and to sabotage them whenever they could. For the larger part, though, the Amsterdam population largely ignored this call.
