On 24 August 1939, as tensions escalated between Britain and Germany, No. 73 Squadron was mobilised for war. It was intended to send the squadron to France as the Air Component of the
British Expeditionary Force (BEF), designated as part of No. 60 Mobile Wing along with
No. 1 Squadron. On 8 September 1939, the Second World War now underway, it deployed to France, initially to
Le Havre-Octeville aerodrome in
Normandy. On 10 September 1939, Kain flew his first operational patrols, covering ships disembarking the BEF at
Cherbourg, without making contact with the enemy. The weather prevented flying for much of the next two weeks and his squadron moved to an airfield near
St. Omer towards the end of the month. From there it moved to
Rouvres, near
Verdun.
Phoney War No. 73 Squadron's new base was close to the border between France and Germany, and No. 60 Mobile Wing was attached to the
Advanced Air Striking Force (AASF), comprising several squadrons of
Fairey Battles of
Bomber Command. The following months saw little offensive activity in the air; this stage of the conflict was known as the
Phoney War. Despite the squadron's proximity to the German border, there was little contact with the enemy and few successful interceptions. By this point, Kain was a
section leader in No. 73 Squadron, with responsibility for two wingmen. On 8 November, while on patrol, he spotted a
Dornier Do 17 bomber above and ahead of him. As the Do 17 began to climb to , Kain pursued, made two attacks, and observed several strikes by his machine guns. With his Hurricane showing signs of strain, he attacked again and the Do 17 dived steeply. Kain followed but pulled out when he saw fabric peeling off his wings. The bomber crashed into the small village of
Lubey, northwest of
Metz, exploding on impact and killing the crew. It was the first aerial victory of the war for No. 73 Squadron and also for a pilot from one of the
Dominions. The event was widely reported although, due to the RAF prohibition of the naming of its personnel in the media, Kain was not identified as the successful pilot in British newspapers. Instead he was simply referred to as a 21-year-old New Zealander. Weather conditions affected the flight operations of the wing, now re-designated as No. 67 Wing, for several days, but Kain had a successful encounter on 23 November, near
Conflans, when he shot down another Do 17. It was one of four German bomber and reconnaissance aircraft claimed as destroyed by No. 73 Squadron pilots that day. There was little flying from December to February due to the weather. Kain spent some of this period in England on leave with Joyce Phillips, a theatre actress he had met while completing his flight training in 1937. He had been corresponding with her for some time. On returning to the squadron, he temporarily took command of one of its
flights. The weather still permitted occasional patrols; in late January his flight encountered a
Heinkel He 111 medium bomber but Kain's guns failed to fire. This was later put down to them being affected by the extreme cold. His aircraft received damage from the He 111's defensive armament, and on landing was found to be irreparable. Kain relinquished command of the flight at the end of January, when its regular leader returned from leave. By early February 1940 the thaw was well underway, but this affected the runway of the aerodrome which was prone to bogging, impacting flight operations for the next few weeks. Kain was
mentioned in dispatches on 20 February 1940 for his efforts pursuing the He 111 that he sighted late the previous month. Weather conditions improved on 1 March 1940, and the following day Kain became involved in a
dogfight with two
Messerschmitt Bf 109 fighters while in pursuit of some He 111s. He destroyed the first Bf 109 but the second damaged his engine with cannon fire before departing. Over the German lines when the attack took place, Kain glided from to reach French territory. When his damaged engine caught fire, Kain prepared to bail out but had to re-enter the cockpit when he realised his parachute strap was not in position. The flames went out and Kain glided on to a forced-landing at Metz. His Hurricane was a wreck and he had to be flown back to Rouvres by a
Bristol Blenheim in the evening. The encounter was reported by the
BBC in its main radio bulletin later that day; Kain was not named and only referred to as a New Zealander. A few days later, identified as
Cobber, he completed a BBC Radio interview that was broadcast on 9 March 1940. Reporters from the United States were not so restricted and his identity was becoming known in his home country. Kain was soon back on operations and, at the same time, the squadron was re-equipping with updated Hurricanes. In mid-March he was informed of his impending award of the
Distinguished Flying Cross (DFC), in recognition of the action earlier in the month when he had shot down his first Bf 109. It was to be the first such award to a pilot of Fighter Command. He promptly took ill with
German measles and was hospitalised for several days. He did not return to operational duty until 26 March. That day, in the early afternoon he led a section on a defensive patrol over the German lines and encountered a group of Bf 109s. He managed to destroy one Bf 109 and then a second, but shortly afterwards his Hurricane's engine was damaged by a cannon strike from another Bf 109. With his aircraft on fire, he bailed out with shell splinters to his left leg, a bullet-grazed left hand and burns to the face. Landing in
no man's land, he made his way to a nearby village. He soon encountered French soldiers and after satisfying them as to his nationality, he was treated by a doctor and driven back to Rouvres in the evening. Shooting down the two Bf 109s in this action made him the RAF's first
flying ace of the Second World War. He remained relatively anonymous to the British public, his identity continuing to be simply
Cobber when his exploits were reported. The wounds from his latest encounter forced him off flying duties for a few days. During his convalescence the citation for his DFC was published in the
London Gazette. It read: With the announcement of his DFC, the anonymity he had previously been afforded was no longer possible. There was significant public interest in Kain, his endeavours being widely reported in the United Kingdom and in the Dominions; one newspaper correspondent described Kain as "carrying the Dominion banner across the German frontiers in grand style". Kain went on leave to England on 2 April, intending to spend time with Phillips. Much to his irritation, the couple had to deal with intense media interest during his leave. While in England, he and Phillips announced their engagement, and tentatively set a date in July for the wedding. Kain returned on 14 April to his squadron, which was now based with the rest of No. 67 Wing at
Reims and tasked with the protection of the AASF headquarters. Tensions were high as a result of the
German invasions of Norway and Denmark, and the
Luftwaffe had increased its presence along the French border with Germany. The squadron was shortly back at Rouvres when the expected fighting in France did not occur. Kain was initially stood down from flight operations so did not undertake his first patrol until 21 April. Two days later he and his flight encountered a
Messerschmitt Bf 110, which Kain damaged, but was surprised by three Bf 109s which shot down two Hurricanes in return. Kain saw little flying duty for the rest of the month, due to poor weather.
Battle of France On 10 May 1940, the German forces launched the
blitzkrieg through the Low Countries and France. No. 73 Squadron was immediately involved, as several Hurricanes scrambled to deal with a number of German bombers. At around 6:00am, Kain engaged and shot down a
Dornier Do 215, one of nine that he sighted near Metz. He encountered another seven on his return to Rouvres but had exhausted his ammunition in the earlier action. The squadron was ordered back to Reims later in the morning, and assembled there by 2:00pm. Despite the airfield being bombed later in the afternoon, the squadron flew several defensive patrols that day, Kain flying two of them. He flew a defensive patrol the next morning, then a mission escorting bombers of the AASF to a target at
Wiltz. On the last patrol of the day he shot down a Do 215; cannon shells from a Bf 110 damaged the fuselage of his Hurricane. The airfield at Reims was bombed again on 12 May, but this did not affect the squadron's operations, and it flew several missions in the afternoon. While escorting some Fairey Battles on a raid north of
Sedan, Kain spotted a
Henschel Hs 126 reconnaissance aircraft that he pursued and destroyed over
Bouillon. Over the next two days,
Luftwaffe activity around Sedan increased in support of the tanks of
Panzer Group Kleist crossing the
Meuse. The squadron encountered several flights of bombers during operations. Kain had no successful engagements on 13 May to add to his official tally of destroyed aircraft but the same day a newspaper reported that he may have destroyed as many as eleven enemy aircraft, and Kain himself had "lost count". Officially he shot down his tenth enemy aircraft, a Bf 109, the next day. , another flying ace of No. 73 Squadron On 15 May, Kain's section encountered a Do 17 and began to initiate an attack. Without firing his guns, Kain saw the crew of the bomber promptly bail out to leave the now pilotless bomber to fly on deeper into France. Casualties in the squadron were now mounting, with four pilots missing or killed in action and a fifth invalided from flying. This saw Kain given command of one of the squadron's flights. The next day, the squadron moved to
Villeneuve while Kain led his flight in a covering patrol to help protect the shift to the new base. Despite flying several patrols, there were no encounters with the enemy until the afternoon of 17 May, when Kain came across a group of Bf 110s; he damaged one and later destroyed a Bf 109 that disrupted his attempt to attack a
Junkers Ju 88. It was a particularly busy day; the end of it, he had accumulated thirteen hours in the air. The pace of the German advance saw another move by No. 73 Squadron, this time to
Gaye, east of
Paris, on 18 May. The next day, the entire squadron took part in a defensive patrol during which it met a group of German bombers, He 111s and Ju 88s, with an escort of Bf 110 fighters. The British fighters attacked and Kain shot down a Ju 88 and then a Bf 110. Towards the end of the engagement, he destroyed a He 111. Seven German aircraft had been destroyed for the loss of three Hurricanes, whose pilots all survived to return to the squadron. By now, No. 73 Squadron's pilots were extremely fatigued from extensive operations and minimal rest. Several fresh pilots soon arrived and Kain helped with their introduction to operational flying. On 22 May he received orders to return to England with several other pilots to take on instructional duties. On arrival in
Le Bourget on 23 May, from where the group of pilots were to travel to England, Kain and another pilot were ordered to immediately report back to No. 73 Squadron. Once back at Gaye, the two pilots were put on administrative duties and Kain did not fly again until 25 May. That day he led a section in a morning patrol, during which he destroyed a Do 17 but had to then make an emergency landing back at Gaye due to damage inflicted on his Hurricane by machine-gun fire from the bomber's rear gunner. The next day, in a replacement Hurricane, he shot down a Hs 126 near Bouillon. The situation in France was now deteriorating; the French army was defending the line along the
Somme and
Aisne with the fighter squadrons of the AASF operating in support, while the BEF was being evacuated from Dunkirk. Kain's focus for 26 May was introducing new pilots to operational duties. The following day, the squadron was operating from a forward base at
Boos-Rouen, alongside
No. 501 Squadron. It was the subject of a bombing raid during which Kain met
Ginger Lacey, who later became one of the RAF's highest scoring flying aces of the war. According to Lacey's biographer, the two were sheltering in what turned out to be a petrol dump. Later in the day, while on a patrol over Boos-Rouen, Kain shot down a Do 17. By this time Kain was very fatigued. Many of his fellow pilots had become casualties or been sent back to the United Kingdom, leaving him as one of the few still remaining of the squadron's original flying roster. Other pilots noted he was increasingly preoccupied and nervous. Although he flew patrols on 28 May, Kain saw little action and for the next two days he was grounded by No. 73 Squadron's commander. He resumed flying on 31 May, leading a section in an uneventful mission providing cover for Fairey Battle bombers attacking German forces southeast of Reims. The first two days of June were quiet, but then the squadron received orders to move to Le Mans and operate from an advanced airfield at
Échemines. Kain led a flight of Hurricanes there early in the morning of 3 June; they then covered the move of the ground crew and administrative staff to
Le Mans. He did not fly the next day and flew a single patrol on 5 June, protecting the airfield. He sighted a Bf 109 and pursued it to near Reims, where he shot it down.
Final flight On 6 June, suffering nervous exhaustion and fatigue, Kain and another long-serving pilot of No. 73 Squadron received orders to return to England as soon as replacement personnel arrived. A group of pilots arrived the next day for allocation to units of the AASF; four were assigned to Kain's squadron, freeing him to return to England. In front of a group of his squadron mates who gathered at the airfield at Échemines to bid him farewell, he took off in his Hurricane to fly to Le Mans to collect his kit. He then began to perform some low-level aerobatics. On the third of a series of "flick" rolls, he misjudged his altitude and hit the ground heavily. He was thrown from the Hurricane's cockpit and died when he struck the ground some distance away from his crashed aircraft. Kain was originally buried in Troyes Cemetery on 8 June but after the war, his remains were moved to the
Commonwealth War Graves Commission's Choloy War Cemetery, near
Nancy. His parents were advised by telegram within two days of his death; his mother and younger sister,
Judy Kain, were in transit to England at the time to attend his wedding to Phillips; Judy was to be a bridesmaid. The BBC reported that he was "killed in action" on 10 May. Later in the month, when the RAF published its casualty lists, Kain was recorded as being killed on active service, rather than in action. As the RAF's first recipient of the DFC and its first flying ace of the war, Kain had a high profile in Britain and the Dominions and his death was widely covered in newspapers. ==Legacy==
