Among Greg’s collection of photos from 1918 is a vertical aerial view dated 30 June 1918 and entitled “S. Mametz”, presumably an abbreviation for South [of] Mametz. My first thought was that this referred to the village of that name a couple of miles west of Aire-sur-la-Lys and not much further north from Rely. But, despite the village being on the doorstep of 42 Squadron’s airfield, I couldn’t reconcile the photo with a present day aerial view on Google maps.
It was only when I purchased a set of digitised trench maps of the Western Front and learnt to read First World War map references that I realised the answer. The line in the photo’s titling strip that reads 62d.F.11.12.17.18 is a reference to four 1,000yd squares on map sheet 62d – which lie just south of another village of the same name, near the Somme and a couple of miles east of Albert. So the photo relates to Mametz-en-Picardie, which is 44 miles (71 km) southeast of Rely, not Mametz-en-Artois.
Aerial ViewsThen and Now
Here are Greg’s photo and the equivalent view today on Google maps:

The settlement visible in both photographs is Carnoy. Mametz itself is just off-camera, to the top left.
It isn’t clear how the photo from the Somme theatre came to be in Greg’s collection. It isn’t particularly clear even why it was taken, other than for general reconnaissance purposes. Possibly it was taken for the forthcoming Final Allied Offensive. Mametz had seen major action two years previously in the Battle of the Somme, and in fact the village was taken from the Germans in fierce fighting on 1 July 1916. For an account of its capture, see this article from The Long, Long Trail website:
Since late March 1918, Mametz had been back in German hands. This was as a result of Operation Michael – their major push westwards towards Amiens in the Spring Offensives. It was not to be under British control again until it was liberated in August 1918. The Final Allied Offensive began on the 8th of that month.
Mametz is about 4 miles (6½ km) north of Bray-sur-Somme, where a German kite balloon was photographed on 15 May 1918:
The negative number in the titling strip is 205.v.1521. I’m grateful to Timothy Slater (who blogs here and tweets here) for the following information in reply to a tweet of this post:
@GregsWar both this photograph and your previous kite balloon photo were taken by 205 Sqn RAF (previously 5 Sqn RNAS). At the time they were flying DH4s on bombing missions for V Bde RAF. I can’t identify any obvious links between 205 & 42 Sqns though.
An improvement in the weather meant that today’s Counter Battery Patrol could go ahead more or less as planned, but it was marred by engine trouble. (If it’s not one thing, it’s the other.) So Air Mechanic Corkhill came up for a test ride in the afternoon. And there was time for some correspondence.
Sunday June 30th. C.B.P with Lt Watkins. Engine nothing great, sent FL FR UD (10.30am).
Received parcel of mags & stockings. Wrote home.
5.30 pm. Took up mechanic with E.27 for engine test. Engine apparently OK.
“Sent FL FR UD”
This was the weather report that Greg sent at 10:30am:
The weather continued to interfere with the work of 42 Squadron. Following yesterday’s cancellation of a shoot, today the weather forced Greg down 10 minutes after take off for a Counter Battery Patrol. Also, Lt Ives is posted to the Home Establishment.
Saturday June 29th. CBP at 8.am with Lt Pring. Weather very dud, came down after 10 mins.
In Other News…
Today’s Routine Orders contain the news that Lt. Edward Leslie Ives, seconded from the West Yorkshire Regiment to the Royal Flying Corps and Royal Air Force, was posted on 28 June 1918 to the Home Establishment:

Lt Ives is seen here with Lt Whittles in their flying kit next to an RE8 at Rely:

Another Counter Battery Patrol, in which Greg was twice switched to new targets, another four bombs dropped, some “pretty hot Archie”, and an intriguing order about sheet tin.
Thursday June 27th. CBP 8 – 11 (8.40 – 10.45). Four bombs dropped, caused small fire. Archie very persistent & pretty hot.
Sent FL FR FD & got to 6,000 ft. Engine rough but picked up & ran very well.
Got X twice from CWS.
…means that Greg twice was given the signal X from the squadron’s Central Wireless Station. ‘X’ meant ‘change to new target’. The X (formed of ground strips of cloth) would be followed by a description of the target. Sounds a bit like he felt was being messed around.
Sheet Tin
The day’s routine orders from the CO, Major Hunter MC, had an interesting entry about sheet tin, which was obviously of some value:
42 Sqn Daily Orders 27-06-1918 page 1
42 Sqn Daily Orders 27-06-1918 page 2
Recovery of sheet tin from Biscuit, Tea and other large tins
Arrangements having been made to sell all sheet tin which is in good condition and which is not required by the British Armies in France, it is necessary that as uniform a method of recovery as possible should be adopted.
Tins are to have their tops and bottoms removed entire, after which the bodies are to be opened up at the joints, i.e., at two diametrically opposite corners. the sheets thus produced are to be pressed flat, bundled in twenties and tied with wire or hoop iron.
The tops and bottoms are to be similarly bundled.
The joints can be opened by hating on an iron plate over a brazier. When the solder in the joint runs, the parts of the tin can be shaken apart.
Special care is to be taken that only sufficient heat is used to make the solder run. Too much heat will spoil the tinned surface and render it unfit for sale.
To prevent deterioration from rust, it is very important that tins should be dealt with as soon as received and should not be left exposed to damp after packing (4000/40 (Q.B.1).)
(G.R.O. 4326, dated 21.6.18).
One might reasonably wonder why “the British Armies in France” might have any use for sheet tin themselves. In fact, one use was to make reflective signal discs in the gas mask haversacks of the infantry:
Haversack signal disc used by Allied troops. From Michael Meech, ‘A Short History of Contact Patrols’ Cross & Cockade International 40(2) 116-127 (2009)
The discs could be deployed by troops in forward positions, so that RAF patrol aircraft on infantry liaison duties (so-called ‘contact patrols’) could see their position and transmit this information to the relevant headquarters.
Another Counter Battery Patrol, and more bombs dropped today; and more water in the carburettor, so an early return:

Date: 26.6.18
Hour: 11.00
Machine type: RE8

Diary
Wednesday June 26th. CBP. Dropped four bombs on houses. Late up & early down – water in carburettor.
Nothing to indicate where the bombs on houses were dropped, but it was probably somewhere in or around German-occupied Merville.
2nd Lt Roche
This was to be 2nd Lt Anthony Berthon Roche’s last flight as Greg’s observer. He was evidently still with 42 Squadron at least until 7 July 1918, according to the records of http://www.airhistory.org.uk/rfc/people_index.html, but Greg’s own papers contain no more information about him.
Back on Counter Battery Patrol after recovering from the flu, with Lt Roche (also recovered), meant a 5:30am start that was rewarded with a direct hit with a bomb on a bridge near Merville. Mac (Lt. Hugh McDonald), who died yesterday, was buried later in the day.

Diary
Tuesday June 25th. CBP at 5.30 am. Very heavy mist. Dropped bombs on bridge near Merville, (direct hit). Observer fired 100 rounds behind Merville.
Heavy low bands of clouds appeared about 6.45 to windward.
Engine became very rough owing to water in carburettor so came home. No Archie. No Huns.
Good landing.
Developed a cold as after effect of P.U.O.
Mac buried.
“Dropped bombs on bridge near Merville, (direct hit)”
An opportunistic departure from a counter battery patrol. Which bridge was it? Hard to tell, as there are so many, as this map extract shows:
Extract from a 1:20,000 map of Merville, May 1918 edition, with trenches revised to 19 June 1918. German works in red. Numbered squares are 1,000 yards. Map credit: IWM/TNA/GreatWarDigital
Merville still has still lots of bridges. One of today’s tourist information boards proudly says:
As the heart of the town is surrounded by water, it can only be reached by crossing one of the seventeen bridges.
It seems unlikely that even a direct hit with one of the 20 lb Cooper bombs that were carried by an RE8 would actually have brought a bridge down. And Greg would surely have proudly said so if he had done. (Spoiler alert: he did on a later occasion!)
Water in Carburettor
A recurrent problem, with the heavy mist and low cloud.
Lt. Hugh McDonald (Mac) Buried
Lt. Hugh McDonald lies buried at plot III.D.33 at Aire Communal Cemetery, next to his observer 2nd Lt. Cuthbert Alban Marsh at III.D.34.
After yesterday‘s crash on take-off from Rely, Marsh and McDonald both died in hospital. Greg did not fly – his final day off flying after the flu.
Monday June 24th. Marsh & Macdonald [sic, should be McDonald] both died in hospital. Marsh buried in afternoon. Did not fly.
So neither of them made it. 2nd Lt. Marsh, who had had such a lucky escape earlier in the month, had celebrated his 24th birthday just two days earlier, on 22 June 1918. Lt. McDonald was 19, the same age as Greg. A reminder, if one was needed, of how dangerous flying was even before anyone wished you harm.
Greg’s first day out of bed (just) after the flu was a bad day for the squadron, with a crash at Rely aerodrome.
Diary
Sunday 23rd. Got up, & walked round a bit feeling groggy. Macdonald [sic, should be McDonald] & Marsh spun into the ground & caught fire, both rescued & taken to hospital.
McDonald & Marsh Crash at Rely
Lt Hugh McDonald (as his name was spelt in the official report) was the pilot.
And 2nd Lt Cuthbert Alban Marsh was the observer, and was also Greg’s observer on his near-disastrous first day on the Front, when they crashed in crops at Trézennes. On that occasion, Marsh was thrown clear:
There were two hospital facilities at Aire-sur-la-Lys at the time. User mhifle of The Great War Forum says that the 54th Casualty Clearing Station came to Aire on 16 April 1918. This CCS was also known as the ‘1/2nd London CCS’. He gives its previous locations with the BEF in France as:
Hazebrouck 1 April 1915 to 31 July 1915
Merville 1 Aug 1915 to 28 March 1918
Haverskerque 29 March 1918 to 15 April 1918
At Aire, the 54th CCS joined No 39 Stationary Hospital, which was there from May 1917 to July 1918 according to The Long, Long Trail. So McDonald and Marsh may have been taken to one of these hospital facilities.
“British Casualty Clearing Station”
The Greg’s War collection includes the following aerial photograph captioned “British Casualty Clearing Station”, which is otherwise unidentified.
High-angle oblique aerial photograph from the Greg’s War Collection entitled “British Casualty Clearing Station”. Click for larger image.
It is possible that this was the 54th CCS at Aire (maybe with No 39 Stationary Hospital also in shot). The landscape looks similar to that just west of Aire, upstream along the Lys valley, near the village of Mametz – Mametz (Pas de Calais) that is, not Mametz (Somme).
A high-angle oblique view created in Google maps. (It’s not entirely successful, as Google has not 3D-imaged the area.) The aspect is looking northeast from just south of the Route de Mametz. Click to go to Google maps to see the location.
But I’m not entirely sure that this is the same place. In this instance, it’s hard to tell how much the landscape has changed over the years. Without any hard evidence of where the photo was taken, and without even knowing just where in or around Aire the 54th CCS was located, I can only identify it provisionally.
Another day in bed as Greg’s Spanish Flu, aka Merville Fever, continued. Still no flying for him. But what was the origin of Spanish Flu?
Diary
Saturday June 22nd. Stayed in bed all day.
Origin of Spanish Flu
After yesterday’s excursion into epidemiology, here’s a bit of a voyage into virology. (We’ll return to aviation soon enough.)
Let’s get one thing out of the way first: the origin of Spanish flu is probably not Spain. It is generally thought that the name came about because Spain’s neutrality in the First World War merely permitted more extensive reporting of the pandemic. See Trilla et al.Clinical Infectious Diseases47(5) 668–673 (2008) (https://doi.org/10.1086/590567) for more.
We now know – but in 1918 they didn’t – that the causative agent of flu is a virus. At the time, it was thought to be caused by a bacterium, Haemophilus influenzae, which is now known to be the cause of various other conditions, including some cases of bacterial meningitis.
Viruses
Like all viruses, influenza virus isn’t really a living entity. It’s a package of genetic material (in this case RNA rather than DNA) wrapped up in a protein-studded lipid (fatty) coat. It can’t reproduce on its own. It can only replicate by infecting a host cell and hijacking the cell’s replication machinery. The infected host then churns out vast quantities of progeny virus, and the cycle begins again.
Today we know what the virus looks like. Here is an electron micrograph of a recreated form of the 1918 Spanish Flu virus:

Surface Proteins and Subtypes
Among the proteins studding the lipid coat of the virus particles (which are in the order of 100 nm in diameter), two that are important for the way that the virus infects its host cells are haemagglutinin (abbreviated HA or H) and neuraminidase (NA or N). Haemagglutinin is involved in the virus binding to the host cell, and neuraminidase assists in viral trafficking. Here’s a schematic picture of a flu virus particle:

Although there are three kinds of influenza virus, A, B and C, it is only influenza A that poses a serious threat to public health. The 1918 so-called Spanish Flu was an example of influenza A. We now know (see below) that it was a subtype known as H1N1, so called because it contains haemagglutinin of subtype 1 (of 16 known subtypes) and neuraminidase of subtype 1 (of 9). Formally, the Spanish Flu virus is therefore known as 1918 A(H1N1) influenza.
Reassortment
When a flu pandemic arises, it is often because of genetic reassortment of the virus. This arises when two different viruses infect the same individual (human or another susceptible species such as pigs or birds). Because the RNA in the nucleus is in different segments, these segments can reassort to give a new genetic combination. In this way, an H1N1 virus might reassort with an H5N3 virus to give an H5N1 virus, say (not a random example, but that is another story). And the human immune system might not have ‘seen’ this reassortment before – at least in the recent past – and therefore have no effective immunity against it.
And the Origin of Spanish Flu is…
…actually not clear. It seems that the reassortment mechanism just discussed did not give rise to the Spanish Flu virus in 1918. Taubenberger and colleagues, working in the mid-1990s with archival influenza autopsy materials collected in the autumn of 1918, sequenced the RNA of the virus and determined it to be an H1N1 subtype and similar to a bird flu virus from an unknown source. (For a review, see Taubenberger & Morens “1918 Influenza: the Mother of All Pandemics” Emerg Infect Dis. 2006;12(1):15-22 (https://dx.doi.org/10.3201/eid1201.050979)). Similar to a bird flu virus, that is, but not exactly the same: it had a mutation, or mutations, that enabled it to infect humans – and pigs. So this proposed bird flu-like virus seems to have been new – immunologically speaking – both to us and to pigs.
It has to be said that not everyone goes along with the Taubenberger bird virus origin theory. A lively debate in the pages of Nature testifies to that. And even Taubenberger says that it is not just a question of a single mutation arising in a pre-existing H1N1 bird flu. That theory is discounted by the large number of mutations found between the 1918 virus and known bird flu viruses. For the moment, the answer to the question “what is the origin of Spanish Flu?” is the unsatisfactory “we don’t really know”. But the bird flu theory is still a contender.
A Live Issue
Intriguingly, this is not merely a question of historical interest. The legacy of the 1918 Spanish Flu is still with us today. The reason that Taubenberger & Morens called the Spanish Flu pandemic in 1918 “the mother of all pandemics” in the title of their 2006 review article is that, in their words :
All influenza A pandemics since that time, and indeed almost all cases of influenza A worldwide…, have been caused by descendants of the 1918 virus.
Yet another long shadow cast from the years of the Great War.
