Casgliad Crawford - Casgliadau Bach, ond Pwysig o Awyrluniau






Mae gan un o’n casgliadau bach ond pwysig o awyrluniau y geiriau “CRAWFORD A.P.” ar gefn y printiau.

Osbert Guy Stanhope Crawford (1896 – 1957) oedd un o’r rhai cyntaf i ddefnyddio awyrluniau i ymchwilio i nodweddion archaeolegol yn y dirwedd a’u dehongli.

Bu’n astudio daearyddiaeth yng Ngholeg Keble yn Rhydychen, ond mireiniodd ei grefft wrth wasanaethu yn y Rhyfel Byd Cyntaf. Cafodd ei anafu yn ystod y brwydro a’i anfon yn ôl i Brydain – ddwywaith – ond dychwelodd i wasanaethu gyda’r Corfflu Hedfan Brenhinol. Roedd ei ddyletswyddau cartograffig yn cynnwys defnyddio awyrluniau o’r ffrynt i gynhyrchu cofnodion cyfoes o systemau ffosydd.

Oherwydd ei ddawn a’i brofiad cafodd ei benodi’n Swyddog Archaeoleg cyntaf yr Arolwg Ordnans, lle bu’n gweithio o 1920 hyd ei ymddeoliad ym 1946. Cafodd yr Athro Peter Grimes (a ddaeth yn un o Gomisiynwyr CBHC yn ddiweddarach, ac yna’n Gadeirydd) ei benodi’n gynorthwyydd iddo ym 1938.


Mae 53 o brintiau ffotograffig yn y casgliad, sy’n dod o wahanol ffynonellau, gan gynnwys y Llu Awyr Brenhinol a Phrifysgol Caergrawnt. Mae’r awyrlun cynharaf yn dangos ardal islaw copa’r Wyddfa a dynnwyd ar 11 Mehefin 1923.

Aerial Archaeology in winter – sunshine and rainbows over Anglesey





Low winter sunlight, combined with low vegetation and bare woodland, is a rare time for the aerial archaeologist hunting for earthwork archaeology and unrecorded monuments. This was especially true in Wales this winter where there was seldom a break in the gales and storms. Occasionally the sun did break through —and when it did, Toby Driver was able to get airborne to record scheduled monuments and known archaeological sites in winter conditions, as well as scouting for unrecorded sites in low, raking light.

One particularly stunning set of views of Anglesey was obtained on 11 February 2016 during a brief ridge of high pressure. Although it was raining on arrival at Caernarfon Airport, and the flight was brought to a close by heavy showers later on, for two hours Anglesey was bathed in glorious low winter sunlight with even the occasional rainbow. The flight proved valuable for documenting some of Anglesey’s stunning coastline and prehistoric monuments like Din Llugwy hut group, as well as later industrial monuments and landscapes along the north coast. The following views offer a flavour of some of the archaeological sites recorded.

Plas Gwyn prehistoric settlement and field system, on a hill to the south of Benllech, was originally discovered during Royal Commission aerial survey in 1999. The group of roundhouse footings can be seen enclosed within a polygonal boundary (AP_2016_0172).

Din Lligwy Iron Age and Romano-British hut group on eastern Anglesey is one of the most accessible sites of its type in north Wales. The settlement has impressive stone-built roundhouses alongside rectangular buildings (AP_2016_0241).

British Aerofilms Photo Used By Luftwaffe In February 1941 Bombing Raid Of Swansea





Between 19 and 21 of February 1941 Swansea docks were the target of a sustained bombing by the Luftwaffe. A large portion of the centre of Swansea was very badly damaged, and the human cost was astonishing. Two hundred and thirty people lost their lives, and over four hundred were injured.


The campaign has been the subject of numerous publications, such as the excellent work “The Three Nights’ Blitz” by J.R. Alban and “Eye of the Eagle” by Nigel A. Robbins (copies both held by the Royal Commission’s library).

Such a focused series of continued bombing raids over enemy territory requires meticulous planning and intelligence gathering. RCAHMW staff noticed that a captured WWII-era Luftwaffe low-level oblique aerial photograph annotated “Geheim” (Secret) and labelled as “Kings Dock u. Prince of Wales Dock” looked a little familiar.



A check through the Aerofilms collection of the area revealed the original photograph was taken in September 1933 (Ref. WPW043061). Aerofilms was the world’s first commercial aerial photography company, and started trading shortly after the First World War.

This find is proof that the German authorities were purchasing aerial photographs of the UK before the outbreak of hostilities in September 1939. An interesting twist that visuals intended to promote Swansea docks for its industrial capacity were later used in an attempt to destroy it.

Note:

The Aerofilms Collection is a unique archive of one million aerial photographs dating from 1919 to 2006. The collection was acquired for the nation in 2007 by English Heritage and the Royal Commissions on the Ancient and Historical Monuments of Scotland and Wales, supported by the Heritage Lottery Fund. The earliest 95,000 images have been conserved and made available online at www.britainfromabove.org.uk and all the Wales images are available on Coflein. http://www.coflein.gov.uk/cy/chwiliad+cyflym/?simple_keyword=Aerofilms&action=site&z=0&zz=0&order_by=ASCRELEVANCE

Remembering The British Women Who Were To Be The First To Track A Rocket By Radar …







A photograph from Mrs Ranson’s album showing her colleagues at work on the range – National Army Museum, ref: 2014-10-20 111748

Take a break from work out on the firing range, posing for official photographs, and relaxing…. four photographs recently discovered at the National Army Museum shed light on the lives of Women’s Auxiliary Territorial Army (ATS) personnel who worked at the Ynyslas top-secret rocket testing range at the end of World War II.

The photographs, donated to the museum by Mrs M. Ranson, are of the small team of highly skilled Experimental Gunnery Assistants who helped track the trajectories of prototype rocket missiles, developed to respond to Germany’s flying bomb technology.

In 1945, a new Guided Missiles Project (under the leadership of Sir Alwyn D. Crow, CBE, ScD, Director of Guided Projectiles, Ministry of Supply) brought together some 40 civilian and service personnel—from the Radar Research Defence Establishment (RRDE), Signals Research and Development Establishment (SRDE), Sir Frank Whittle’s Power Jets (Research and Development) Ltd, and the fuel companies Asiatic Petroleum Company (formed by Shell and Royal Dutch Oil Companies) and Laporte Chemicals Ltd — to push rocket technology forward.

The firing range was manned by nine officers and 202 ordinary ratings (excluding cooks and ratings) under a Superintendent of Experiments (S of X). Only one official document survives relating to the trials — the minutes of a visit on 2 January 1946 by Major L W Jubb, the chairman of the Guided Projectile Working Committee. After a tour of facilities with the S of X, Lt Col T. L. G. Tod, Royal Artillery, discussions centred on how photographic observations might be improved using the Akeley and Ascania cameras operated by Women’s ATS staff.  However the oral testimony of Margaret Herterich, in the collections of the Imperial War Museum, reveals how the tests were conducted:
‘Our main work was the start of experimentation on rockets, the beginning I believe of the Blue Streak, the British rocket. Four of us were trained as Kinetographers on modified kinecameras as used in the film news industry. The first instruction was in one of the loading bays where a system of knots and rope-pullage had been devised. We pulled the ropes in a fashion to follow the knots, although we didn’t know why we were doing it at the time. Eventually we worked these two kinecameras mounted on posts. Each was worked by two girls for bearing and elevation. After loading and switching on, we followed the flight path and booster-drop of rockets fired from a ramp on the range. The films were taken back to the dark-room where we four girls wound them on large circular reels and developed them. We were responsible for the results of the experiments costing thousands of pounds. The film was then evaluated, frame by frame, through a grid machine and then plotted onto the longest piece of graph paper you’ve ever seen. The trajectory was then studied by the Officers.

We knew that we were working on something special when we girls received letters from the Ministry of Supply, asking if we would like to go to Woomera, Australia, to carry on the work of the Blue Streak Rocket. Our officers were excited about this work as they had just received some new Canadian radar equipment. Knowing that I had been an Operator Firing Control on radar in the Ack-Ack, they invited me into the new set to be, as they said - ‘The first woman in Britain to see a rocket on radar’. We didn’t see a thing!’
You may not have been able to see the rocket on radar that day, but it is on record that your commander, Lt Col Todd, greatly lamented the loss of his skilled Women’s ATS personnel when they were  demobilised in 1946 (document ref: AVIA 48/16, National Archives, Kew).

The Ynyslas experiments contributed to Britain’s post-war space progamme, which lead to the establishment of the European Launcher Development Organisation in the early 1960s - the forerunner of today’s European Space Agency.
 
We would love to hear from anyone who had a relative who also served at MOS EE AA Ynyslas. Or who could tell us more about the women featured in Mrs Ranson’s photos.

A very special thank you to the Ben Fellowes, Public Information Curator, National Army Museum. The Museum is closed for major refurbishment until 2016, so we are especially grateful that staff were still able to provide access to the album.
