The technical problems of bomb aiming were massive for all air forces. The Luftwaffe began the war with an ambition of pinpoint accuracy for key targets and expected electronic systems to guide their attacks.
The Heinkel He 111 aircraft was an interim bomber that carried a light bomb load and had a cramped crew cabin making space for the bomb aimer challenging, as can be seen from this early illustration. The main Luftwaffe bomb sight was technically advanced for the 1930s but less effective in the more demanding flying conditions over wartime Britain.
The early attacks on the ports were daylight raids and allowed for accurate bombing. This near miss of four bombs at Llandarcy oil storage (below) was from a daylight raid in 1940. The switch to night time bombing and the need to bomb from higher altitudes led to more inaccuracy and error. Pinpoint targets such as grain mills, lock gates and warehouses, or ships in the docks were missed but the surrounding streets of the Welsh ports suffered badly from the inaccurate bombs.
This is my protocol from my civil service days. I used this (in whole or part) to educate, plan, or review monitoring programmes. Monitoring is hard to plan and very hard to do. In the UK, funding is often rewarded for a ‘project’ but the concept of understanding whole life costs is rarely appreciated. The money wasted on community lottery funding schemes is heartbreaking as projects are devised, money spent, and then there is no conception of maintenance or longer-term costs. Locally, I know of over £3m in lottery funding that has been wasted in ill conceived schemes with no oversight and unqualified charities signing cheques with no regard for quality or care.
As a Gateway Reviewer I was often brought in too late in a failing scheme, and my role then was merely to record the errors and failures. If we had been brought in at strategic planning or business case, it was better.
This plan was my basic script for programme oversight and I found I could frequently reverse engineer it to interpret what had gone wrong or explain how a programme failed.
Mandated monitoring. Imposing a requirement on a programme as part of their funding and appraisal system.
Question-driven monitoring. The dreaded ‘research question’ approach of many academic bodies, often a waste of talent and time and merely to get a tick in a box. This is the stuff that is funded, completed, and locked away for ever. The best use of resources is through good quality research questions. However, I used to read questions that were long and incomprehensible…so how do you answer them…or better yet learn from them?
As a reviewer for government, I saw monitoring programmes that were ineffective or failed completely. It doesn’t help that many in the biodiversity sector see monitoring as a ‘management activity’ which is unrelated to scientific research.
The failures I saw
Short-term funding preventing planning. Question-driven monitoring pushed staff to plan backwards…data first, question later. Also, data management was often dreadful with no structure or futureproofing for reviewers. A monitoring timescale can be a decade…who stays around for ten years on a program in biodiversity? Nobody…which makes succession planning vital, but never done. Loss of key personnel and the corporate amnesia that follows was harmful for staff and quality, but often treasured by politicians and managers who want a predecessor to own mistakes.
The Shopping List approach. An impossibly long list of monitoring topics instead of a sharp defined monitoring objective. It is backlog planning in programme speak.
Failure to agree on what to monitor. Often politicians and managers want career-enhancing metrics…not realities.
Flawed assumptions. A very human desire to compare one set of data to something elso or associate with something else that looks good, but has incompatible data. The temptation to ‘salt’ data on key metrics (e.g. bats, reptiles, invasive speciers) was overpowering. An overclaim is more likely to get published etc.
It is a big graphic, so you may need to enlarge it.
The Luftwaffe had a wide range of weapons available to drop on urban areas in the early years of the war. Lock gates, coal mines, and food storage all had buildings with varying levels of resilience and required different tactics to destroy them. The ports were susceptible to damage in some aspects such as power stations or cranes but generally quite hardy in the face of attack. Larger bombs over five hundred kilogrammes in weight with hardened steel noses were need for the power stations and lock gates. The Luftwaffe was always short of these types of bombs. However, the real terror weapon was the incendiary bomb shown below.
This one kilogramme bomb (the ‘Elektron’) was dropped in thousands on the Welsh ports but it was only ever effective in destroying houses and shops. Creating a firestorm to kill civilians was eventually developed by the RAF and perfected by the US Army Air Forces. The Luftwaffe were experimenting in firestorm tactics in late-1940 and the raid on Swansea in February 1941 shows the early firestorm approach with early arrival of incendiary bombing followed up by high explosive bombs to kill firemen and civil defence staff. The damage to Swansea (shown below) was typical of intensive firestorms which could not be extinguished because firemen were killed and their pumps destroyed. Burning buildings collapse and obliterate the streets with rubble. The RAF intensively investigated these early Luftwaffe raids and based their own strategic campaign against Germany on the nature of these early raids.

Cilfái’s connectivity to other wildlife and natural habitats is not just a concern, it’s a massive issue. The dangerous main roads dominate the wider extent, west towards the river and north towards what was the Enterprise Zone. Within the woodlands, further development for bike paths, walking trails and cable car routes are all immediate risks for ruinous fragmentation. The width of paths and firebreaks and cableways and how we manage the woodland edge habitats are crucial. Cilfái’s wider nature network must be urgently mapped and managed using the ten well-known best practice principles (Crick and others 2020a: 91–101).
1. Understand the Place. Understanding the community and the natural networks that are in place.
2. Create a Vision. Create a future that is understandable and engages the biggest stakeholders, usually the local communities, animals and plants, and those responsible for caring for and maintaining the land.
3. Involve People. Communication, engagement and consultation are tremendously important. Do we see that commitment from local politicians?
4. Create Core Sites. The central Cilfái woodland is our core site.
5. Build Resilience. This is protection against climate change-related events such as drought, torrential rain, wildfires, and temperature extremes. I describe some of these in the book.
6. Embrace Dynamism. Nature changes constantly. Change can happen in a matter of minutes: a tree blows down, a stream bursts its banks, or a rockfall changes the shape of the land. We can’t keep spending money on keeping things ‘as they are’. Is expensively recreating a nineteenth-century landscape that relies on money, gardening, water and stable weather and climate (as they do at Penllergare Country Park) even possible in the modern world? We must accept and adapt to our situation, not the situation we would like to be in.
7. Encourage Diversity. There is genetic variability, species diversity, ecosystem diversity and phylogenetic diversity. Diversity is not distributed evenly on Cilfái. The ecosystem we see building on the hill results from 50 years of growth and change.It should be allowed to develop naturally. The notion that a local Council or a private tourism company can care for the land is an outrageous conceit.
8. Think ‘Networks!’ Plants, animals, and people move and live in connected networks.
9. Start Now, but Plan Long-term. Short-term is about 3 years, long-term is about 50 or more. Nobody knows what the world will be like in 50 years.
10. Monitor Progress. We can’t understand change if we don’t observe it constantly. A 3-day ecological survey by a non-local contract ecology firm on behalf of a foreign tourist company doesn’t cut it.
However, there will always be uncertainty about what Cilfái can contain because it is always prone to extreme disturbance.

Above: The western part of the woodland with areas of particular attraction to birds and wildlife highlighted in shades of Brown. These areas are open or semi open and also show strong characteristics of ‘woodland edge’ or ‘Stand A’ structures (see Annex 7). These areas have their origin in polluted soils from slag tips or fire damage from wildfire attacks. The old coal adits and leats provide damper cover than the surrounding woodland and frequently act as biodiversity hotspots because they retain moisture in drought conditions. These Brown areas are the current centres of natural regeneration. The woodland cover in these areas will not be necessarily native species, it is far more likely to be the ‘Cilfái mix’ of coniferous, native and invasive non-native. These areas are rapidly becoming reptile hotspots and also very strong presences of foraging bats.
The steelworks of the Welsh ports were of obvious interest to the early Luftwaffe investigators. Iron and steel were strategic materials for all sides. The Dowlais steelworks in Cardiff was a huge target. In fact it was so big that it was difficult to work out exactly where to hit it to cause most damage. The largest high quality bombs were reserved for targets like this (500kg or more), with hard steel noses to penetrate concrete roofs. Incediary bombs were not very effective against industrial targets.
Above: The Dowlais steelworks as depicted in the Militärgeographische Einzelangaben from 1940. A difficult target to attack which required special bombs of larger size and hardened casings to penetrate concrete walls and floors. Incendiaries were practically pointless against a steelworks. There was also a need to attack at a lower altitude to increase accuracy. The presence of a couple of barrage balloons would frequently discourage crews from flying al lower altitudes.
The copper smoke from White Rock was horrendous. Black, acrid, greasy and opaque. It killed everything it touched. The chemical composition of the Cornish copper ore meant that once burnt with Kilvey’s bituminous coal, released vast quantities of sulphur dioxide, hydreogen fluoride, sulphrous and sulphuric acids. in the 1840s, the Vivian’s Hafod Works were releasing 188 tons of Sulphuric Acid daily into the Swansea Valley.

I’m taking a University class out tomorrow to look at some industrial housing history around Hafod and Landore. Housing history was the central theme of my research in the 1990s amd I must have surveyed and mapped hundreds of Glamorgan houses as I worked to understand industry, landscape and the housing needs of the early coal and metal industries.
Shape is one of the most important features of early (pre-1919) houses and it became a bit of a party trick when I could guess for other people the decade in which their original house was built. Although many of Swansea’s earliest industrial houses were swept away in the 1920s as part of slum clearance, quite a few of the classic examples still remain. Beyong the boundary of the original County Borough of Swansea, neighbouring local authorities did not clear their older houses and many survive in villages, cwms, and valleys near the pits and factories they served.
These are the handouts fr0m ‘Housing History 101’ from my teaching days. I suppose these types of documents (and clip art!) are history themselves now LOL.
Port Talbot (Aberafan) has a long history as a port, although much of the town’s historic identity is swallowed up by the dominant steelworks . Coal was moved down the Afan Valley to a site originally known as Llewellyn’s Quay, probably from the 1600s or earlier. By the 1750s, a tram line had replaced the pack horse route, and by 1811, iron was also being moved through the valley. Copper ore was imported for the copper works at Cwmafan by the 1830s, and a wharf near Llewellyn’s Quay was built to handle ore (the original Copper Works Wharf).
Port Talbot was identified as a port of interest because of the two large integrated steelworks. The dock was also considered vulnerable because it could be destroyed by bombs on the lock gate and entrance.

The term ‘resilience’has become a key concept in our landscape management. Resilience in woodland is becoming a broader and more important topic as climate change starts to bite.
In its current form, Cilfái is resilient. Yes, people burn it every year, but that results in more biodiversity hotspots as the burnt patches grow back with local species of trees and vegetation that are much more resilient to fire and drought.
Anything done to the woodland should be to enhance resilience…not knock it back with imported plants, plastic tree tubes and high maintenance planting schemes.
Diversity in the Cilfái woodlands can range froim genes and species to habitats and landscapes. The complexity of the Cilfái woodlands ecosystem will always be limited compared to a woodland that is older or has not been polluted. Still, the pollution history of the hill makes the ecosystem special and probably even unique.
Above: The seaward slopes of Cilfái are increasingly susceptible to windstorms which easily topple the trees that often have poor anchorage because of the soil conditions. The resulting deadwood (both prone and standing) provides useful food and shelter for many animals and insects. The natural regeneration quickly takes over a windblown space and colonises fast with the ‘Cilfái mix’ of local species. Incredibly, this site on the proposed tourism development is a bat hotspot.

The aircraft was a Do 17P from second Staffel of Fernaufklärungsgruppe 123 Der Adler mit dem Fernrohr,(The Eagle with the Telescope). This image is from that initial mission. The open fields of Mumbles are seen in the fine summer of 1940 with the open lands of the commons on the left side. The wreck of the SS Protesilaus can be seen on the sands at West Cross in the Bay.
Clyne Valley is still intensely wooded and the fields and gardens of western Swansea are still free from the urban density that we see today.
