"Meanwhile, hordes of refugees from the invaded regions to the east continued to pour into Berlin. The Wehrmacht told them to stay where they were until transport to the south and west could be improvised... In the midst of this misery and disorder a terrible blow from the sky fell on Berlin. On February 3 some 1,000 American bombers, escorted by 900 fighters, in 45 minutes dropped a blanket of 2,072 tons of bombs on the center of the city. The fighters swept on east to the Oder River, where the pilots could see the Russian guns all along it pouring shells into the Nazi lines. Stockholm correspondents reported that thousands of refugees in the packed city were killed in the raid."
