Small-scale Rhodesian reconnaissances erroneously estimated the ZANLA force to be 2,000 men strong. The 91st Aero Squadron, therefore, took care of all of the long-range day reconnaissances. The second (his first bar) was for conducting several personal reconnaissances of enemy positions. Heavy clouds and constant rains increased the difficulty of reconnaissances. SOE mounted some reconnaissances of northern Sumatra (in the present-day province of Aceh). Reconnaissances sent by First Army and IV Corps fell victim to flak and enemy fighters. At least until 09&colon;20 (French time), air reconnaissances indicated that the position was unoccupied. During January 1945, "Bluegill" made reconnaissances in support of American liberation of the Philippines.
