The '''Polish Fighter Squadron''' ({{langx|pl|I/145 Polski Dywizjon Myśliwski}}, {{langx|fr|Groupe de Chasse Polonais}}), also known by its designation '''GC I/145''', was the largest [[fighter plane|fighter]] unit of the [[Polish Air Forces in France and Great Britain|Polish Air Forces in France]]. Formed of Polish pilots who evaded capture by the Nazis and the Soviets in the aftermath of the [[Invasion of Poland]] of 1939, the unit was initially earmarked to be sent to Finland as part of the aborted plan of Allied intervention in the [[Winter War]]. Eventually it took part in the [[Battle of France]] defending the French skies along with the allied armies.

== History == [[File:Józef Lucjan Kępiński.jpg|right|150px|thumb|Józef Kępiński]] Initially the December 1939 annex to the [[Franco-Polish Alliance]] Treaty establishing the [[Polish Armed Forces in the West]] proposed the creation of four Polish squadrons: * 1st 'Warsaw' Fighter Squadron under Lt.Col. [[Leopold Pamuła]] * 2nd 'Kraków-Poznań' Fighter Squadron under Maj. [[Mieczysław Mümler]] * 3rd 'Dęblin' Fighter Squadron under Maj. [[Józef Kępiński (aviator)|Józef Kępiński]] * 4th Fighter Squadron under Maj. [[Eugeniusz Wyrwicki]]

[[File:Caudron CR.714.png|thumb|right|Caudron C.714 plane of GC I/145 in Polish markings (note the distinctive [[Polish Air Force checkerboard|''szachownica'']] sign); June 1940]] The third squadron started to be formed at [[Bron]] near [[Lyon]] (modern [[Lyon–Bron Airport]]). In early February 1940 the newly created squadron was earmarked to take part in the [[Franco-British plans for intervention in the Winter War|Allied intervention in the Winter War]], together with [[Polish Independent Highland Brigade]]. Because of those plans, the new unit was unofficially called the Finnish Squadron. It was equipped with [[Morane-Saulnier M.S.406]] fighters, the workhorses of French aviation, while [[Caudron C.714]] fighters were used as trainers. As soon as the unit was to reach Finland, it was to be re-equipped with Caudron fighters entirely. However, in March 1940 Finland signed a cease-fire with the [[USSR]] and the plan was aborted.

Meanwhile, the training of the Polish squadrons in France went slowly and by April only the 3rd 'Dęblin' Sqn. was ready for service. As on 6 April 1940 the French Ministry of Aviation officially created the '''Polish Fighter Squadron of Warsaw''' ({{langx|fr|Groupe de Chasse Polonaise de Varsovie}}), the 3rd was renamed and became the first operational Polish air unit on French soil. By the end of April the unit received the first 20 M.S.406 fighters and started guarding the skies around Lyon.

On 10 of May the German invasion of France started. On that day the [[Lyon–Bron Airport]] was struck twice by enemy air raids. The squadron did not suffer any losses and was moved to a reserve airfield at [[Mions]]. As the French had no available M.S. 406 fighters to spare, on May 12 the Ministry of Air decided to re-equip the Poles with hopelessly flawed Caudron C.714 fighters waiting in [[Vélizy – Villacoublay Air Base|Villacoublay]] near Paris. The pilots received 35 new planes on May 18 and already the following day suffered the first casualty: [[Witold Dobrzyński]] was killed in an air accident. After just 23 sorties, adverse opinion of the fighter was confirmed by front line pilots who expressed concerns that it was seriously underpowered and was no match for contemporary German fighters.

On 25 May, only a week after it was introduced, French Minister of War [[Guy La Chambre]] ordered all C.714s to be withdrawn from active service. However, since the French authorities had no other aircraft to offer, the Polish pilots ignored the order and continued to fly the C.714. Despite flying a fighter hopelessly outdated compared to the [[Messerschmitt Bf 109]]E, the Polish pilots scored 12 confirmed and three unconfirmed victories in three battles between 8 June and 11 June, losing nine in the air and nine more on the ground. Among the aircraft shot down were four [[Dornier Do 17]] bombers, but also three [[Messerschmitt Bf 109]] and five [[Messerschmitt Bf 110]] fighters. [[File:PSP Dywizjon 302.svg|thumb|right|The emblem of the [[No. 302 Polish Fighter Squadron]] featured the designation of the GC I/145, from where most of its initial crew came]] On 2 June the unit was moved to [[Dreux]] ([[Vernouillet Airport|Vernouillet Airfield]]) 80 kilometres west of Paris. The following day a [[Flight (military unit)|flight]] of three aircraft (Maj. [[Lionel de Marmier]], Lt. [[Tadeusz Czerwiński]] and Lt. [[Aleksander Żukowski]]) attacked a flight of three [[Heinkel He 111]] bombers taking part in German [[Operation Paula]], shooting down two. Around that time some of the pilots were detached from the squadron and pressed into a newly formed fighter unit created to defend the seat of the [[Polish government in Exile]] in [[Angers]]. The unit was re-equipped with [[Bloch MB.152]] fighters.

On 5 June the 1st escadrille of the Squadron was attached to GC I/1 under Maj. Robilon at [[Bretigny, Côte-d'Or|Bretigny]], but was returned to Dreux the following day. On 8 June five C.714s led by Maj. [[Józef Kępiński (aviator)|Józef Kępiński]] attacked a group of roughly 20 Messerschmitt Bf 109 fighters. Despite German numerical and technical superiority, the Polish pilots scored one probable kill. The following day the entire Squadron was re-based to [[Bernaby]], some 50 kilometres South-West of [[Rouen]]. There it joined two other French squadrons: GC II/10 and GC III/10. Around 14:00 the unit, led by Maj. Kępiński left on patrol. Around 15:00 near [[Vernon, Eure|Vernon]] it encountered a group of roughly 25 [[Dornier Do 17]] bombers escorted by approximately 20 Messerchmitts. The Germans lost three Bf 109 fighters (Lieutenant Główczyński, Cpr. Parafiński and one downed jointly by Lt. Godlewski and Cpr. Zaniewski). In addition, Capt. Wczelik downed one of the bombers. However, the GC I/145 also suffered losses: three pilots were killed (por. Jan Obuchowski, ppor. Lech Lachowicki-Czechowicz and kpr. Edward Uchto), one wounded (por. Julian Kowalski), while four more were forced to land away from the home base. Altogether the unit lost four pilots and seven fighters.

On 10 June the squadron moved back to Dreux. En route a flight of 12 planes under Maj. de Marmier attacked a group of 15 Dornier Do 17 bombers and 10 Bf 109 fighters. Ppor. Jerzy Czerniak scored two Dorniers, ppor. Aleksander Żukowski and por. Tadeusz Czerwiński scored one each. However, Józef Kępiński, the commanding officer of the squadron was heavily wounded, the unit also lost three damaged and one aircraft destroyed. The following day the pilots were moved further away to [[Sermaize]], some 15 kilometres south of [[Etampes]] and two days later to [[Châteauroux]], where some of the losses were replaced by [[Bloch MB.152]] fighters. The command over GC I/145 was taken over by Capt. [[Piotr Łaguna]].

As the situation of the French Army was becoming increasingly desperate, on 17 June it was decided to split the Polish fighter unit and attach it to two French units badly needing reinforcements. Eight pilots under Capt. Wczelik joined the GC I/1, while eight under Lt. Wilczewski joined the GC I/8 (both squadrons equipped with [[Dewoitine D.520]]). The following day a flight of three planes (WO Delagay, Capt. Wczelik and LSgt Markiewicz) shot down a lone Heinkel He 111. This was the last victory of the Polish unit during the French campaign. The following day the pilots were evacuated by cars to the port of [[La Rochelle]], from where they were transported to England. Thirteen pilots of the GC I/145 then joined the newly created [[No. 302 Polish Fighter Squadron]] fighting alongside the [[Royal Air Force]].
