On 26 November, O'Connor held a meeting at the Baggush Box after the completion of "Training Exercise No. 1", a rehearsal for Operation Compass, in which attacks on fortified positions had been practised, the troops not being told that the positions were replicas of the Italian camps at Nibeiwa and the Tummars. The officers with O'Connor reported that the method laid down in "The Division in Attack" was too slow and sacrificed surprise, leaving the attackers vulnerable to air attack. The Air Officer Commanding in Chief, Air Marshal Arthur Longmore, was being pressured from London to send formations to Greece and to provide air cover for Operation Compass, he stripped the air defences of Egypt of two squadrons and a flight, which he placed at O'Connor's disposal.
