There are other problems. The MIS staff is too small for the amount of work that needs to be done. There were only 105 civilians processing and translating Magic traffic on December 7, 1941; as of February 1, 1943, there are 1,754 working at a signals center called Arlington Hall. (By the war’s end, there will be 13,000 men and women working on a wide variety of signal intelligence, including German police signals, direction finding, map making, etc.)
