While the command of the IV Company was signalling passing planes in the hope that they were Allied aircraft about to make an airdrop, the partisan Braconi was hit by shell fragments and died two days later. Company commander Bruno Acciai was also wounded in this episode. On the same day, German documentation concerning the 10th Army around 19.00 hours, reports the shooting down of 5 Allied twin-engines by anti-aircraft Flak positioned in Bibbiena. In all likelihood, the partisans of the IV Company, who had been expecting an airdrop over Pratomagno for some time (it never happened), mistakenly attracted the attention of a German reconnaissance aircraft involved in airspace control. It should be noted that in the same period, German airmen and soldiers were being informed about the signalling systems set up by the Resistance to indicate where supplies were to be dropped.
