Who was right? Into the last days of the 9th Australian Division in Tobruk

In retrospect, we can now say that Churchill's complaints about the 9th Australian Division removal were overblown. There were no great effects by the removal. If the German air force had been attacking during the withdrawal, the situation could have been critical, but they were not. Operation Crusader was not materially affected by the Australian relief operation. The issues that caused the operation to be in jeopardy had nothing to do with the Australians. The issues were British problems, not Australian. Churchill was more concerned about the political impact of delaying the offensive in North Africa. The British at the time were unaware of the impending Japanese attack planned for December 1941. That was going to cause the most trouble for Churchill and the British forces.
Towards the end of the Australian participation in the defense of Tobruk, the Salient was the most dangerous area. From August to September 1941, the 2/24th Battalion worked to re-position the wire to help the 2/13th Field Company. They did the work on the left side of the Salient from "18 August to 1 September". They moved the wire on the right side of the Salient starting on 8 September and finishing on 25 September. When moving the wire, the presence of German anti-personnel mines took a toll.
We find that by September, there were some peculiar behaviors in place. For one thing, there was what the Australian historian called "live and let-live" to some extent by the Australian and Axis troops. Most of the time, German patrols were defensive in nature. They only rarely made attempts to penetrate the Australian positions. One exception occurred on 11 September, when a German patrol was spotted and ambushed. They killed three men and eventually captured a man who seemed to be lost. He was a member of what eventually was called the 90th Light Division. In September 1941, they were known as the Division Afrika zbV. The 9th Australian Division intelligence view on this was that the new division had been brought in to free up the armored division motorized infantry, so that they could go back to providing support to their divisions.
When the British 16th Brigade arrived in Tobruk, they had already served with the Australians in three previous campaigns. They had participated in the first campaign in the desert when they had defeated the Italians and captured Cyrenaica. They had also fought in Crete and finally in Syria. This is based on the account in Vol.III of the Australian Official History.
