By 15th August 67 Field Regiment were advancing on Florence. Alongside them was C Troop London Passenger Transport Board Territorials HAA . They parted company on 22nd August when 67 moved forward to stay within range of their infantry, leaving the HAA Troop to share the position at Galluzzo with an American Battery of Long Toms. Early on 2nd September the Gordons out on a strong patrol to Prato with tanks and a FOO Party from 266 Battery encountered heavy opposition when out of range of 67 Regiments guns. The Heavy Anti Aircraft guns of C Troop London Passenger Transport and their neighbouring American Long Toms opened fire under direction of 266 Battery FOO's quietening the opposition and allowing the patrol to withdraw. It was the first time the Gordons had experienced Anti Aircraft air burst as artillery and were very impressed with the results.
