Because there were an unknown number of refugees in Dresden at the time of the Allied attack, it is impossible to know exactly how many civilians perished. After the war, investigators from various countries, and with varying political motives, calculated the number of civilians killed to be as little as 8,000 to more than 200,000. Estimates today range from 35,000 to 135,000. Looking at photographs of Dresden after the attack, in which the few buildings still standing are completely gutted, it seems improbable that only 35,000 of the million or so people in Dresden at the time were killed.
