War time service

Norwegian campaign

Fliegerkorps X was the only Luftwaffe fleet to take part in the campaign and I Gruppe StG 1 was the only component of StG 1 to take part.[1] Part of the Corps' order of battle was I. Gruppe StG 1, equipped with longer ranged Junkers Ju 87R as well as the standard Ju 87Bs. The unit was initially based at Kiel-Holtena.[2] On 9 April I./StG took part in raids against Oscarsborg Fortress after it sank heavy cruiser Blücher. Soon afterwards the gruppe was takes with naval interdiction. Its primary target was the Royal Navy's Home Fleet. The same day, the unit hit the 600 ton torpedo boat Aeger in the engine room. It was run aground and scuttled.[3] The units first loss occurred in 19 April. While attacking HMS Cairo, Leutnant Karl Pfeil and his gunner Gerhard Winkels were shot down and captured near Namsos. The same day, a British raid by Fleet Air Arm Blackburn Skua and Fairey Swordfish Aircraft destroyed six Ju 87s near Trondhiem/Vaernes from carriers HMS Ark Royal and HMS Glorious. Ju 87s did manage to sink anti-submarine trawlers Siretoco, Jardine and Warwickshire. HMS Bittern was badly damaged and sunk by HMS Juno. Later, on 1 May 1940, I. Gruppe failed to hit Ark Royal during an interdiction against British naval forces off the coast.[4] Staffelkapitan of 2 Staffel, Oberleutnant Heinz Bohne claimed to have hit the carrier (he did not) and failed to mention in his report that he lost one of his Ju 87s (Oberfeldwebel Erich Stahl and Unteroffizier Friedrich Gott) to two Sea Gladiators of No. 802 Squadron RAF. This was the only loss on 1 May.

The next few missions on the afternoon of 1 May and 3 May, the Ju 87s had more success. The French large destroyer Bison was sunk along with HMS Afridi by I./Sturzkampfgeschwader 1 on 3 May 1940 during the evacuation from Namsos. Bison's forward magazine had been hit killing 108 of the crew. Affridi, who had attempted to rescue Bison's survivors was sunk with the loss of 63 sailors. On 4 May Ju 87s of I. Gruppe sank Norwegian steamers Blaafjeld, Sekstant, Pan and Aafjorld.[5] On 8 May Gruppenkommandeur Hauptmann Paul-Werner Hozzel, Oblt. Elmar Schaefer and Lt. Martin Möbus and veteran observer Unteroffizier Gerhard Grenzel, became the first Stuka crews to receive the Knight's Cross of the Iron Cross. Grenzel was the first NCO in the Luftwaffe to receive the award.[5]

On 24 May 1940 I. Gruppe sank the Norwegian trawler Ingrid in Bodo harbour. The Gruppe suffered one loss; Feldwebel Kurt Zube, to a No. 263 squadron Gladiator. He was rescued by German forces. I. Gruppe also took part in the Battles of Narvik. Heinz Bohne and his gunner was killed on 2 June 1940 over Narvik. He was the victim of Sgt. H H Kitchener and Flt Lt A T Williams of No. 263 Squadron RAF. Two Ju 87s were shot down on the morning of the 2 June 1940. Lt Klaus Kuber and his gunner were killed, the victim of a No. 43 Squadron RAF Hawker Hurricane. Mk. I flown by Sgt B L Taylor whilst Feldwebel Hans Ott and his gunner Sonderfuhrer Brack fell victim to Flg Off. John F Drummond.[6]

Western Europe, 1940

No units of StG 1 took part in the western campaign in 1940. Stab./StG 1, I./StG 1 and III./StG 1 (which had I.St/TrG 186 specialised anti-shipping unit under its command) were committed to the Unternehmen Adlerangriff (Operation Eagle Attack) offensive under Hugo Sperrle's Luftflotte 3. All units were based at Angers, France, under the operational command of General der Flieger Wolfram von Richthofen. The total strength of the Geschwader was 80 Ju 87s with 55 operational.[7]

On 14 July 1940 StG 1 engaged various convoys heading westward through the English Channel. II./StG 1 and IV.(St). Lehrgeschwader 1 sank five ships between them, including HMS Boreas and HMS Brilliant. Two II. Gruppe machines were lost. The same day III. Gruppe Ju 87s were forced to abandon a raid on Portland Harbour when engaged by RAF fighters. They suffered one shot down and two damaged.[8]

The last major convoy action took place on 8 August 1940 against Convoy CW 9 (Peewit), comprising 20 merchant ships and nine naval vessels. Two Stuka attacks were organised. The first involved StG 1 who lost two Ju 87s and two damaged. A second attack from 60 Ju 87s of I. StG 1, III./StG 2 and III./StG 3 resulted in the destruction of four merchant ships and damaged seven. In exchange three I./StG 3 Ju 87s were lost and another four damaged.[9] A third attack sank Empire Crusader.[10]

In mid-August StG 1 was ordered to cease missions owing to the Ju 87s unacceptable losses. It continued operating over the channel until February 1941.[11]

The Balkans

I Grupp./StG 1 took part in the Balkans Campaign. Supported by 1,200 aircraft, 27 German divisions (including seven Panzer) of the Army made short work of the Yugoslav Army, and then the Greek Army and the small British Army contingent sent to assist. I./StG operated from bases in eastern Romania.[12] The Gruppe also participated in attacks on Malta's convoys.[13]

North Africa

I Gruppe was rushed to North Africa in February 1941 to support the Afrika Korps (Deutsches Afrikakorps).[14]

Eastern Front

StG 1 participated in most of the battles in the Soviet Union. At the end of Barbarossa, StG 1 had lost 60 Stukas in aerial combat and one on the ground.[15]
