The battle sequences cannot be explained unless the reader understands that the whole German position consisted of pairs of interlocking sections. This was obviously not understood by the commanders at the beginning of the battle. These were the open, watery southern outskirts of the town linked to the main built-up area under the heights; the town linked to the hillside above it crowned by the Monastery; the front and back of the Monastery were linked together, and the back of the Monastery was joined to M. Castellone, a long, exposed flank. These five zones had to be attacked simultaneously to prevent mutual reinforcement. Piecemeal attacks therefore, were fore-doomed to failure.
That is the tactical dimension. Similarly, the operational dimension has also to be viewed as a whole, and as a (somewhat dislocated) continuation of the First Battle of Cassino.
Finally, we emphasise our debt to Martin Blumenson. Although our account of AVENGER differs from his in important respects, were it not for his labour, and that of his colleagues, revisionary studies such as ours would be immeasurably more difficult.

2nd NZ Div/Corps G Log for 1400 Hours 12 February shows American locations: “1/141 reported 100 yards beyond crest of Point 593 towards Point 569.2/142 on ‘Hill 468’.” (Hill 468 was Massa Albaneta. It was not a hill but a spot height in the valley below Point 593. The 142nd had never held it, but were halted at the pass on Cavendish Road above it.)
The US units were the 135th and 168th Infantry of the 34th Division and the 141st of the 36th Division.
7. Gruenther was clearly mistaken about the date and time of the original request for bomber support. By the evening of the 12th Freyberg, at last in possession of the facts of the situation on the heights behind the Monastery, had realised that a postponement was necessary. He would not, therefore, have asked that same evening for air support on the 13th. Clark could not have been aware of the facts, or else he would not have asked for the mission to be delayed until 10 a.m. Disregarding the added misunderstanding about the bomb safety line, Gruenther did not cancel the mission until 10 a.m. on the 13th, and then only in response to the vehement objections of Keyes and Ryder. It should be noted that both Clark and Phillips give the date and time of the original request as p.m. 12th.
8. One inexplicable feature of a dreadfully muddled affair was that although the NZ Corps and the US 2nd Corps were under command of HQ Fifth Army, and the NZ Corps was about to carry out a major, independent operation, albeit in a sector believed to be controlled by the 2nd Corps, the channel of communication carrying the vital information about the timing of the bombing mission was via HQ 2nd Corps and thence to HQ 34th Division, both failing to pass it either to HQ NZ Corps or to HQ 4th Indian Division. Viz., “150158 [i.e., 1.58 a.m., February 15] As far as we know the first bombing will not take place until 1300 [1p.m.]” “150730. Abbey will be bombed this morning between 0930 and 1015,” 2 US National Archives, Suitland, pp. 334–3, 2. (Even if the mistaken belief that Keyes, Ryder et al, were in full operational control on the heights and therefore entitled to overrule the NZ Corps over matters affecting the safety of US troops still obtained in the American camp, the failure to pass such vital information directly to HQ NZ Corps can only be attributed to a disastrous failure in “staff duties”.

When this chapter was being researched Richard Kohn, the Chief of Air Force History, and his staff were undertaking a second-generation study on the component phases of FM 100–20 — “air superiority”, “interdiction” and “close support”. They allowed us to see proof sheets of their publication, Air Superiority in World War II and Korea — a volume in the USAF Warrior series, edited by Kohn and Joseph P. Harahan — in which interviews with senior airmen were recorded. Members of the staff were kind enough to read a couple of draft papers on the subject of army–air cooperation from which this chapter was distilled. Graham was also able to talk to Eduard Mark who was working on interdiction, and with Dan Mortensen on a number of subjects. The Air Force study provided a framework for the chapter.
Sources on microfilm at Boiling are extensive and the drafts and printed versions of numerous formation histories are on the shelves of the library. Historical studies used by the original official historians are available. We list here the more useful to us:

We have attempted to describe a great battle, in all respects except space on the same scale as El Alamein, October 1942, and our account is necessarily condensed. We have not concerned ourselves with the carping of Clark, who bequeathed to the US historians the notion that the Eighth Army was “drawn along” in the wake of the successes of the Fifth, nor with the fraught command relationships inside the Canadian Corps or between Leese and Burns, as neither affected the course of the battle. With regard to Leese, we are much indebted to Nigel Hamilton, who furnished us with much useful information, the fruit of his own research. Otherwise we have relied extensively on the accounts of Anders, Jackson, Nicholson’s admirable volume of the Canadian official history, Ray’s history of the 78th Division, the German sources as listed and Kirkman’s diary.

Notes on Research
This chapter was originally researched in 1970 by Dominick Graham and Nicholas Straker as part of their battlefield tour in the summer of that year. The documentary support on the British side was sparse since the relevant volume of the Official History had not been commissioned. However, Straker wrote a narrative using what had been prepared by historians in the Cabinet Office, Jackson’s Battle for Italy, Orgill’s The Gothic Line, and British regimental histories. By then Nicholson’s volume had been published and much of the documentation on which it was based, German as well as Allied, was available at the Directorate of History, Ottawa. Good regimental histories, such as those of Roy and How (BC Dragoons and New Brunswick Hussars), were also published. This ought to have served to balance the accounts of Jackson and Orgill which tend to concentrate unduly on the operations of the British 5 th Corps, whereas it was the Canadian Corps that broke the German main defensive line, captured Coriano and finally broke through.
In 1983 Brereton Greenhous and William McAndrew of the Directorate of History conducted a battlefield tour to study the actions of the Canadian 5th Armoured Division. Many veterans, including the divisional commander, Major-General Hoffmeister, participated. We have used the papers written for the tour which reinforce our view that a great opportunity was lost. The inherent fault in Leese’s plan was the lack of a reserve he could dispose of flexibly. As a result when the 5th Corps failed to loosen the strong German defence lines near the coast by a series of left hooks, the Canadians, whose role and strength were incompatible, were unable rapidly to exploit their success and help the 5th Corps forward, instead of vice versa.

(Mainly concerning General Burns and his relations with Leese and his own subordinates.) In Folder 7, 604–9, Burns comments:
There did not exist any well-recognised authority with respect to the function of an armoured division when fighting in the Italian terrain. Conditions were completely different from those encountered by 7th Armoured Division in the Desert … General Leese, both at the Liri Valley battle and in the Gothic Line did not exercise the direction that might be expected of an Army Commander. In the former operation General Burns worked with the commander of 13th Corps [Kirkman], who appeared to have more concern with the running of the battle than General Leese. Similarly, in the Gothic Line matters seemed to be left in the hands of the 5th Corps commander.

The war diaries of the units of the Canadian Corps were examined. Their value varies but some contained excellent after-action reports. One of these extra papers is the radio log of the Strathcona’s in their attack on M. Pelosa with the Princess Louise’s Dragoon Guards. Also Brigadier I. S. Johnston’s appreciation for the attack of the 11th Brigade against the Green Line on August 30. There are also good accounts of the attacks of the Cape Breton Highlanders on Montecchio and Point 120 and the Perths and British Columbia Dragoons operations at Point 204.
