During July and August, two new bolometer sites commenced operations near Algeciras and Ceuta. These sites detected Operation Pedestal, a convoy bound for Malta, during the second week of August 1942 and Axis air, sea and submarine attacks led to many losses. Following this engagement, the British Chiefs of Staff Committee again considered countermeasures against the bolometer sites; the Governor of Gibraltar and Special Operations Executive proposed direct attacks on the facilities and the head of the Royal Navy advocated jamming them. During a meeting held on 25 August, the Chiefs of Staff decided to make another diplomatic protest, which was formally lodged with the Spanish Government in October.
