“Some of the lads went to the village last night ran into some Yanks, a rough fight…We have all been issued with ‘Jack knives’ now. … Our C.O. says given ‘em the works lads, and believe me we will.”
This startling account of a planned brawl between a group of British Tommies and American G.I.s in April 1944, sounds more like a West Ham / Millwall clash than the ‘special relationship’ commonly described during the war. The commanding officer giving his enthusiastic endorsement of the fight is particularly disturbing and a far cry from the stiff upper lip officer stereotypes in films of the time. This insight comes from the Censorship Reports. I've used these sources extensively in my research looking at the soldier's experiences of entertainment whilst serving in the Italian campaign. This article explores why these reports were written and how they help the historian to understand the experiences of 80 years ago.

What Were Censorship Reports?
The War Office (like most other military administrations during the war) read a proportion of the personal mail sent and received by the serving troops. This huge bureaucratic task was carried out for two reasons: primarily to enforce operational security and secondly, to assess troop morale, discipline and sentiment. The findings of this work was summarised in regular Censorship Reports, which were distributed across formations fortnightly or monthly. It goes without saying that confidential information should not be shared in letters home that might reveal unit locations, dates, troop numbers, or tactical plans. Regimental officers were responsible for removing these details, but men in the British Army were also allowed to send communications intended for personal family matters that could bypass this process using 'Green Envelopes'.
For example, the G2 Base Censorship units operating under Allied Forces Headquarters (AFHQ) and 15th Army Group systematically examined a statistical sample of approximately 10% of all mail during each fortnightly reporting period.[2] A much higher proportion of ‘Green Envelopes’ were examined as they could bypass the regimental unit officer. For 15th Army Group, based in North Africa and Italy, this involved reading between 22,000 to 28,000 letters every fortnight during the latter part of 1943.
Whilst experiences of individuals varied greatly in any given period of time, depending on their unit, personal circumstances, and overall outlook, the Censorship Reports provided an invaluable barometer for morale by summarising the results of a statistically significant proportion of letters. The following aspects of attitudes were captured:
Fighting Spirit and Psychological Resilience: Tracking troop confidence in Allied leadership, optimism or pessimism about the Allies’ prospects, feelings on the war's duration, operational fatigue from prolonged overseas service, and anxieties regarding redeployment or post-war demobilisation.
Logistics and Living Conditions: For example, food rations, winter clothing, living quarters, and medical services.
Postal Performance: Monitoring mail delivery speeds, lost parcels, and pilferage. Mail was recognised by senior command as having a direct impact on troop morale.
Amenities and Entertainment: Assessing troop reactions to canteens, NAAFI pricing, wireless broadcasts, mobile film units, and live theatrical shows (such as ENSA tours versus unit concert parties).
Inter-Allied and Civilian Relations: Observing sentiments towards Allied partners (e.g. American, Canadian, and Indian forces), Axis prisoners of war, and local civilian populations in North Africa and Italy.
Home Front Concerns: Flagging domestic issues causing anxiety, such as news of strikes in Britain, post-war employment schemes, spousal infidelity, and soldier pay or tax allotment problems.
The Censorship Reports used extracts from personal mail to illustrate the themes they highlight in order to provide a general morale assessment for the formation.
How They Can Be Used?
These regular summaries were shared widely across the different administrative sections of the Army Group, including the Chief of Staff, G-1 (Personnel), G-2 (Intelligence), G-3 (Operations), the Adviser in Psychiatry, Quartermaster branches, and individual Corps and District Commanders. In this way, the Censorship Report became an important source for driving policy updates, changing logistics, or addressing widespread grievances (such as the quality of entertainment).
For the historian today, these sources show what the British Army thought of their morale at the time. For example, using the 15th Army Group censorship reports between June and December 1943, it is possible to plot the fluctuating morale onto a timeline and cross reference this against key operational dates as shown below:
Plotting Censorship Report Morale Assessment to Key Operational Dates June - December 1943
Morale spiked during periods of major operations and dropped consistently in the subsequent six weeks. Unsurprisingly, morale is lower during the hard fighting from mid-October onwards. More specific insights can also be drawn based on extracts of individual letters in the Censorship Reports. For example, looking at the importance of entertainment in the lives of the soldiers, the report for 16-29 February 1944 highlights the number of times men in Italy mention concert parties and film shows in their letters home.[4]
Collapse: A Global History of the Second World War, 1931-41 by Jonathan Fennell
One of my favourite historians, Jonathan Fennell, whose latest book on the Second World War, Collapse draws heavily upon morale and censorship reports from all the protagonists, including China and Russia.[5] Like Crang and others before him, Fennell uses these sources to draw out new perspectives on the conflict, which highlights the importance of the spirit, motivation, and willingness to fight of the people involved. [6] Writing 80 years later, Fennell drew on 925 Censorship Reports based on 17 million letters in his account of the British and Commonwealth morale during the war. This 'X-Factor' provides an additional dimension to the analysis of events that is, in my opinion, much more human and relatable than the traditional economic, technological, and doctrinal lenses of military history. The censorship reports often defy expectations and challenge safer, more conventional assumptions about the Second World War.
