Leaving two OGs with radio near the landing area the main body of the patrol made way to the north/south road where they cut all remaining wires, noting that the wires that had been cut by CHICAGO I had not been repaired. At about 2300 hours while heading southward on the road the lead element of the patrol, being alerted by a noise, took cover. A patrol of eight men riding bicycles was seen going northward. The men in dark uniforms wore boots and helmets and carried rifles over their shoulders. While none of the OGs could see clearly enough to recognize the helmets or uniforms, they thought them to be German, not Italian.
Because of the size of the bicycle patrol
it was assumed that Pianosa was under military control. Therefore, Captain
Catanzaro and his party quietly withdrew to the landing point and then
made radio contact with the boat party giving the "danger"
signal calling for early pick up. They reboarded the MGB at 0115 hours
and returned directly to Bastia.
