Consequently, during 2015 a record 1.1 million refugees and migrants entered Germany, and September was a record month in which between 270,000 and 280,000 newcomers arrived in Germany, according to official figures.
On Wednesday the German magazine Bild reported government sources in Berlin and Vienna, who said that Merkel's government made the unexpected decision after Hungary deliberately misinformed them about the number of migrants waiting to enter Germany.
"We expected one to three thousand people, in a one-time event, no more," Berlin government sources told Bild.
"What was coming to us should have been manageable," said a Foreign Ministry official in Vienna.
One high-ranking EU diplomat said that Orban's move instantly rid his country of Europe's migrant problem.
"On that day, Orban made his country completely refugee-free," they told Bild.
