A message was sent to the Technical Officer of I./ZG 1 confirming that an Fw 190 G-3 (WNr. 160337) had been taken over from "G.A.F. Station (smudge) Land."

The Technical Officer of I./ZG 1 was told that a Fw 190 G-3 (WNr. 160821, “8”) was being handed over to the Luftwaffe land aircraft workshop at Brest-South. At 10.27 hours the same day, "fighter detachment 1/128" reported that this aircraft had stalled while landing at Brest from an “air screening” sortie (presumably for naval forces). The Focke-Wulf had touched down violently and broken the diagonal bracing strut of its left oleo leg. Damage to the airframe was assessed at 8–10% and a replacement was “urgently necessary.” Leutnant Heinz Bichler emerged uninjured, however.

At 13.07 hours on 14 February, an Fw 190 (WNr. 1466, “+10”) was coming in to land at Brest-South after bombing practice. That sortie was cancelled but rescheduled for 13.03 hrs. Failure of electrical circuit meant that its flaps would not come down and it landed at too high a speed. The aircraft itself was about 10% damaged—and again its replacement was urgently necessary—but pilot Lt. Heinrich Greuner was unhurt.

Five days later, 1./SAG 128 was deleted from a Fliegerführer Atlantik signals list and 10./ZG 1 was added. The British Government Code and Cipher School deduced from this that 10./ZG 1 was the “fighter detachment” renamed. This view was reinforced by the knowledge that the “new” unit was based at the same airfield, Brest-South.

On 2 March, Fliegerführer Atlantik announced that four Fw 190s were going to cross the coast at 07.03 hours and only 100 m. altitude in map square 5959. They were due back between 90 minutes and two hours later at the same height and place. That operation was then cancelled but rescheduled for 13.03, all other details remaining the same. The profile of this mission suggests that it too was to provide screening for naval units.

The 10./ZG 1 (now subordinated to X. Fliegerkorps) reported to a Senior Signals Officer that six of its aircraft were equipped with FuG 25A IFF sets.

A report which rather perplexed British Intelligence revealed that five Fw 190s, two officer and four NCO pilots of 10./ZG 1 had left Lyon-Bron along with six non-commissioned and enlisted technical personnel. The analysts had seen no evidence of any prior transfer away from Brest-South where 10./ZG 1 had last been located.

On 11 April, Fw. Rudolf Schoenbach was recommended for the Iron Cross First Class, having completed 118 Fw 190 sorties: 105 over the Atlantic and 13 against French Resistance forces on the Savoy Plateau.
