By mid-1941, Caldwell had flown about 40 operational sorties, but had only one confirmed
kill - a Bf 109. He was perplexed by the fact that he had trouble scoring hits on enemy
aircraft. Whilst returning to base one day, he noted his squadron's aircraft casting
shadows on the desert below. He fired a burst of his guns and noted the fall of shot relative
to his shadow. He realised this method allowed for the assessment of required deflection to
hit moving targets. Further experimentation lead him to acquire the knowledge to assess
deflection needed for a range of speeds. Within a couple of weeks he had attained four
further kills and a half share. Caldwell's method of "shadow shooting" became a standard
method of gunnery practice in the Middle East.
On 29 August 1941 Clive Caldwell was attacked by two Bf 109s North-West of Sidi Barrani.
One of his attackers was the Bf 109 E-7 "black 8" of 2./JG 27 piloted by one of Germany's
top aces, Leutnant Werner Schroer who was credited with 114 Allied planes in only 197
combat missions. Caldwell's P-40 "Tomahawk" of 250 Squadron was riddled with more than
100 rounds of 7.9 mm slugs, plus five 20 mm cannon strikes which punctured a tyre and
rendered the flaps inoperative. In the first attack Caldwell suffered bullet wounds to
the back, left shoulder, and leg. In the next pass one shot slammed through the canopy,
causing splinters which wounded him with perspex in the face and shrapnel in the neck.
Two cannon shells also punched their way through the rear fuselage just behind him and
the starboard wing was badly damaged. Despite damage to both himself and the aircraft,
Caldwell, feeling, as he remembers, "quite hostile" turned on his attackers and sent
down one of the Bf 109s in flames. The pilot of the second Messerschmitt, the renowned
Leutnant Schroer, shocked by this turn of events, evidently made off in some haste.
Caldwell's engine had caught fire, however he managed to extinguish the flames with a
violent slip. He then nursed his flying wreck back to base at Sidi Haneish.
Caldwell's most successful day was the 5th of December 1941 when he shot down five Ju 87s in a single engagement during operation "Crusader". Here is the combat report of that action:
In contrast with the great successes of
Skalski's Circus , Polish pilots' endeavours with
112 Squadron weren't as fruitful. A group of 12 Polish ferry-transport pilots volunteered
for RAF service on 29 August 1941 and after training they joined "Shark" squadron in
February 1942. On 14 February, 1942 the patrolling 112 Sqn RAF and 3 Sqn RAAF encountered a
formation of 32 enemy aircraft and Sec.Ltn. Dula downed an MC 200. In combat with 6 Bf 109
fighters from I/JG 27 on 21 February 1942 three "Kittyhawks" of 112 Sqn were downed, two of
them piloted by Polish pilots: Sgt. Derma and Ltn. Jander. On 13 March 1942 pilots P/O Bartle
(English) and Sgt. Rozanski (Polish) left a formation of 12 "Sharks" in the Tobruk area and
they were caught by surprise and attacked by Oberfeldtwebel Otto Schulz (4./JG 27, MIA on 17
June 1942, 42 victories). Both were downed, but Rozanski luckily escaped his crashed, burning
aircraft. On the following day Sgt. Urbanczyk together with S/L Caldwell got one Bf 109. On
15 March 1942 112 Squadron was moved from the front line to Sidi Haneish for replacements.
Polish pilots didn't return to duty in this unit from 16 April 1942.
Whilst with 112 Squadron, the Australian government asked that he be released to return to
Australia to command a Wing in the defence of Australia. This Wing was to consist of 3
Squadrons of "Spitfires", and Caldwell spent some time with the Kenley Wing before returning
home to acquaint himself with the new aircraft. The Japanese were threatening Northern
Australia, and several Australian towns were regularly being bombed. Caldwell left the
Middle East with nineteen individual and three shared confirmed enemy kills, six probables,
and fifteen damaged.
On his departure from the Middle East, the Marshall of the RAF Lord Tedder wrote of Caldwell: 'An excellent leader - and a first class shot.' On taking up his command of No. 1 Fighter Wing based in Darwin, Caldwell again showed his outstanding fighting abilities and claimed a further eight Japanese aircraft by August 1943. Caldwell's tally was twenty-eight and a half by the time he left the Wing in August and for this feat he received a DSO to add to his DFC and Bar and Polish Cross of Valour.
