It is noticeable in the DEFE3 files (the Ultra material first made public, long before HW5) that the bulk of Luftwaffe traffic in the February-June 1944 period is from Italy, Greece & Yugoslavia. As soon as the Allies land in France, the traffic from there dominates the files. As the situation in Italy stabilises in late summer, traffic falls away to almost nothing even from the few Luftwaffe units that were still there.
