Whatever <strong>the</strong> difficulties, however, destruct ion of French industry was essential. for it figured largely in <strong>the</strong> pl.ms of <strong>the</strong> German war machine. The success of <strong>the</strong> mission may NOVEMBER, 1944 By MAJ. CHARLES D. FRAZER AIR FORCE Overseas Staff be seen in a few tvpical t,ugcts-for example, <strong>the</strong> CAM ball and roller be'lring plant. This conecrn-thc Compagnie d'Application Mccaniqucs -\\',IS a subsicliary of <strong>the</strong> Swedish SKF organil.ation. Its two plants at Bois Colombe and I\TY were capable in pre-war times of producing -+0,000 bearings per day. The wartime production figure rangcd from I :;,000 to 2:;,000 daily. Two thousand workers were employed. From a strategic st.mdpoiut this may have been <strong>the</strong> most important induvtri.i] tnget in Fr.mcc, ~fanubctme of bearings requires higldy skilled labor and it is one industry <strong>the</strong> Ccrm.uis could not dcccutr.ilizc.

The first attack all Bois Colombe destroyed 30 percent of <strong>the</strong> surface structures and 20 percent of <strong>the</strong> machines. Practically all roofs fell in, Orv.ir Custaflson, <strong>the</strong> Swedish manager \vho ran <strong>the</strong> plants under Ccrmun xupcrviviou, called this a very gooc! result. Since 30 operations arc needed to make a herring, this pcrccut.u;c of destruct ion put <strong>the</strong> plant out completely for two months. 1':\'('n after work was resumed production never again got above 12,000 hearings per day.
