1. Summary

The Anglo-Norman forces that were building castles in , as part of their ongoing colonisation, suffered a setback in the period 1094–6 when the Welsh revolted. In 1096 a contingent of Anglo-Norman forces were ambushed by Welsh forces, under the control of Ifor and Gruffudd the sons of Idnerth ap Cadwgan at a place called Aberllech. The battle is briefly mentioned in the Cambro-Latin and Welsh chronicles and does not appear in any other sources. There are no direct clues as to its whereabouts, but two previous suggestions have been proposed, one in Monmouthshire and the other in Breconshire, and a third one also in Breconshire and not previously considered, is also examined here. It was probably the last important Welsh victory against the Norman colonisers in this area, before their eventual overall control.

Battle of Aberllech 1096

2. Narrative of the action

2.1 Prelude and Background

In 1088 Bernard of Neufmarché (c. 1050–c. 1125) headed an invasion into the Welsh kingdom of Brycheiniog from his estates in the Wye Valley region of . By the end of the year he was in possession of , according to a charter of the abbey at .1 Although details are sparse, Bernard seems to have slowly consolidated his conquests in eastern Brycheiniog and had penetrated as far as by 1093, where he began construction on a castle at the confluence of the Usk and Honddu rivers.2 This was the impetus for Rhys ap Tewdwr the ruler of , to attack, for if Bernard was able to establish a castle at Brecon he would then be in a perfect position to attack the kingdom of Deheubarth. Bernard and Rhys met in battle near Brecon and Rhys was defeated.3

Following the defeat of Rhys ap Tewdwr, Bernard’s hold on Brecon was still not fully consolidated and the western and upland parts of the of Brycheiniog remained untamed. In 1094 the Welsh began a concerted campaign of conflict against the French.4 The revolt was serious enough for the king, William Rufus, to gather an army and head for South Wales in the autumn of 1095, ‘but the valleys protected the Welsh, and the king went home empty-handed.’5 In 1096 Brycheiniog, Gwent and Gwynllwg rebelled against the French and slaughtered some of the French as they returned from Gwent, at an unlocated site called Gelli Carnant.6 The Anglo- had begun to build castles in Brycheiniog as a way of consolidating their gains and it was whilst returning from building some of these, the sources do not state where, that the attack at Aberllech took place.

2.2 Battle

All of the primary sources agree that the French were routed at Aberllech by a Welsh contingent led by Ifor and Gruffudd, the sons of Idnerth ap Cadwgan. A similar successful attack had taken place earlier in the year at Gelli Carnant and this is described in similar terms. The context of the chronicles suggest that the attack was in the form of an ambush along a known transit route. The use of the term Aber in the place name suggests it took place near the confluence of two rivers, and a valley site, perhaps heavily wooded, is therefore likely. The Welsh tried to avoid engaging the Norman forces in direct battle and relied upon evasion and ambush in order to defeat the Norman troops.7 An ambush by a small Welsh contingent as the Anglo-Norman forces returned towards lands under their control seems the most reasonable context for the conflict at Aberllech.

2.3 Details of Troops and Casualties

The fact that the ambush at Aberllech made it into the chronicle literature suggests that the numbers involved were sufficiently large to justify its inclusion. As part of the frequent attacks against the Anglo-Normans in the revolt of 1094–8, Aberllech must have seen the defeat of a substantial number of Anglo-Norman troops, but as to exact, or even approximate numbers, it is difficult to judge. The Welsh military unit of the teulu would consist of approximately fifty men and a similar number of Anglo-Norman troops is not unreasonable.8 The source suggest that a majority of the Anglo-Norman troops would have been slain and the Welsh were unlikely to have left the field without some losses, however the lack of information makes it impossible to say for certain.

2.4 Aftermath

The chronicle sources show that, following the conflict at Aberllech, the Anglo-Norman castles remained intact and Bernard completed his castle at Brecon thereby consolidating his conquests in eastern Brycheiniog. The Brutiau refer to the men of Brycheiniog slaying Llewellyn ap Cadwgan in 1099 and a poem to Hywel ap Goronwy, written shortly after 1100, states that ‘The land of Brycheiniog [is] your true right, may everyone see that.’9 This evidence shows that a part of Welsh kingdom of Brycheiniog remained under Welsh control in the years following Aberllech. However, and his followers continued to rule in lowland Brycheiniog and the Welsh never regained the land taken by them, their victory at Aberllech proving to be little more than a minor setback to the Norman colonisation of the region.10

3. Evaluation

3.1 Discussion of Primary Sources

The only primary sources for the conflict at Aberllech are the Cambro-Latin Annales Cambriae and the later Welsh Brut y Tywysogyon. No notice of it is preserved in any surviving poetry and it is too early to appear in any official records.

3.1.1 Annales Cambriae

The battle is mentioned in both the B- and C-text versions of the Latin chronicle Annales Cambriae preserved in London NA E164/1 (c.1300)11 and London British Library Cotton Domitian A.i. (c.1300), respectively. The B-text manuscript at this point is damaged and the probable readings are placed in brackets. The C-text is very clear.

A. Griffiths and P. R. Schofield (eds.), Wales and the Welsh in the , Essays Presented to J. Beverley Smith (Cardiff, 2011), pp.46–55. 7

The Britons of Brycheiniog, Gwent and Gwynllwg made an immoderate slaughter of the French at Celli Darnauc. After a short while […] they were killed by the sons of Idnerth ap Cadwgan in Aberllech.13

C-text Brecheínauc . et guent . et guenlíunc iugum francorum respuunt . sed franci exercitum mouent in guent . et nihil impetrantes uacuí domum redeunt . et in kellitrauant uersi sunt in fugam . Iterum uenerunt in brecheínauc . et castella fecerunt in ea . sed in reditu apud aberlech uersi sunt in fugam a filíís idnerth filii kadugaun.14

Brycheiniog and Gwent and Gwynllwg threw off the French yoke, but the French brought an army into Gwent, and they obtained nothing and returned home empty-handed; and at Kellitravant they were put to flight. Again they came to Brycheiniog, and built castles there, but on their return they were routed at Aberlech by the sons of Idnerth, son of Cadwgan.15

The Annales Cambriae show that the French forces had mixed success in their attempts to subdue Brycheiniog in 1096, losing men at Gelli Travanat and Aberllech. However, it would appear that they were successful in the construction of their castles as no reference is made to these being taken.

3.1.2 Brut y Tywysogyon and Brenhinedd y Saesson

The Latin chronicles, or a similar earlier work that underlies them, form the basis for the later Welsh chronicles known as Brut Y Tywysogyon (ByT). This work survives in over thirty different manuscripts in two versions, known as Peniarth MS 20 and Red Book of Hergest, both compiled in the late thirteenth century. A third version also exists, but in only two manuscripts, known as Brenhinedd y Saesson (ByS), which appears to have been written later, generally contains less original material and interprets its Latin source differently.

Brut y Tywysogyon (Peniarth 20 version) And thereupon the French led frequent raids into Brycheiniog and thought to destroy the land completely. And when they had failed to have their will in aught, they returned home; and then they were slain by the sons of Idnerth ap Cadwgan, Gruffudd and Ifor, in the place called Aber-llech. The castles, however, still remained intact, with their garrisons in them.16

Brut y Tywysogyon (Red Book version) After that the French moved a host to Brycheiniog and thought to ravage the whole land, but, having failed to accomplish their thoughts, as they were returning they were slain by the sons of Idnerth ap Cadwgan, Grufudd and Ifor, in the place called Aber-llech. And the inhabitants stayed in their houses unafraid although the castles were still intact and the garrisons in them.17

Brenhinedd y Saesson And then the French moved their host into Gwent; and they gained no profit thereby, but many of them were slain in the place called Celli Garnant. Thereupon, soon after that, they went with their host into Brycheiniog, and they gained no profit thereby but were slain by the sons of Idnerth ap Cadwgan, namely, Gruffudd and Ifor, in the place that is called Aber-llech. But their castles were left intact, and their poor folk remained trembling in their houses.18

All three versions add details not found in the Latin, most importantly the names of the sons of Idnerth ap Cadwgan, Gruffudd and Ifor. This information helps to locate the sphere of influence of these Welsh leaders and is discussed below in 3.1.4. The note that the castles stood intact builds upon the inference from the Latin texts and the second half of the sentence shows how the three different versions chose to interpret their Latin text.

3.1.3 Anglo-Saxon Chronicle

Although not specifically about Aberllech, it is also worth noting the following extract from the E manuscript of the Anglo-Saxon Chronicle for the year 1096, which shows how attempts to colonise Wales were viewed in England.

Also in this year, the head men who held this land regularly sent an army into Wales, and greatly afflicted many a man with that; but there was no success in that, but the destruction of men and waste of money.19

3.1.4 Genealogical sources

Although not primary sources for the events at Aberllech, the Welsh genealogical manuscripts do provide information about the family of the Welsh protagonists. Gruffudd and Ifor were the sons of Idnerth ap Cadwgan ap Elystan Glodrydd. Elystan Glodrydd is the ancestor of several dynasties operating in southern and the kingdom of Rhwng Gwy a Hafren (between the Wye and the Severn). Although Ifor and Gruffudd do not appear again in the Brutiau, their uncles do and locating their sphere of influence may provide some clues as to the location of Aberllech. Goronwy and Llewelyn ap Cadwgan fought at the battles of Camddwr and Gweuontyll in 1075 and 1077 respectively.20 Neither site has been securely located. Both Llewelyn and Goronwy are named in genealogical material as of the line of Buellt21 and Ieuan ap Cadwgan is named in a genealogy concerning the rulers of Powys.22 A

brother to Ifor and Gruffudd is also mentioned in two genealogical tracts referring to the lines of and in Powys.23 This genealogical information shows that the families’ main sphere of influence and interest was southern Powys. This would make a location nearer the southern boundary of Powys, a more probable site for the involvement of Ifor and Gruffudd.

3.2 Discussion of Secondary Sources

No further references to the battle appear until the first English translation was made of Brut y Tywysogyon by in 1559 entitled . The work was undertaken with the intention of publishing it, but Llwyd died in 1568 with the work still unpublished. Although Llwyd’s original manuscript is lost at least three contemporary copies are known and these were edited by Williams in 2002.

Therefore when they sawe they had all the losse they manned and vittailled the castelles they had before tyme builded there, and returned backe. And the sonnes of Idnerth ap Cadwgan, Griffith and Ivor, meette with them upon the sodeyne at Aberlhech and fill upon them, and slewe the most parte of them, and the rest escaped to Englande and the capteins of the castelles defended them manfully and kept them tyll they were driven by force to forsake them and to save ther lyves and so the auncient dwellers enjoyed their country quietly.24

Llwyd’s translation formed the basis for the first printed history of Wales The Historie of Cambria edited by and printed in 1584. Powel’s text is practically identical to that in Cronica Walliae25 and remained the standard work on Welsh history until the nineteenth century when the Welsh texts of Brut Y Tywysogyon were printed in the Myvyrian Archaiology (1801).26 Aberllech is not mentioned in the unreliable ‘Gwentian Chronicle’, published in the same volume.

The first county history of Breconshire was Theophilus Jones’ History of the County of Brecknock (1808) which mentions it briefly; this is discussed in more detail below. Aberllech continues to be mentioned in passing throughout the nineteenth century, but the next work to add to the study of the conflict is a sentence in J. E. Lloyd’s A History of Wales published in 1911 which suggests a location for the battle.

The men of Brycheiniog, led by Gruffydd and Ifor, sons of Idnerth ap Cadwgan, fell upon another host which had issued from the same region [Glamorgan] and totally routed it at Aber Llech, about three miles north-east of Ystrad Gynlais.27

Lloyd interprets the French troops as coming from Glamorgan, not an unreasonable assumption from the chronicle evidence, and locates the battle at the point where Nant Llech meets the River Tawe. He gives no evidence for the location and we are left to assume that it

Williams (ed.) Humphrey Llwyd Cronica Walliae (Cardiff, 2002), p. 128. 25 David Powel (ed.), The Historie of Cambria (London, 1584), p. 154. 26 The Myvyrian Archaiology of Wales, 3 vols (London, 1801–07). Texts in vol 2. 27 J. E. Lloyd, A History of Wales: From the Earliest Times to the Edwardian Conquest, (London, 1911), pp. 406–7. 10

was the coincidence of a river Llech on a route between Brycheiniog and Glamorgan that led him to site the location so confidently.

William Rees in his study of the lordship of Brecon published in 1916, doesn’t mention the battle at all28 and the next detailed look at the evidence is by Lynn Nelson who provides a context for the conflict at Aberllech, but adds no more evidence then previous writers, in his 1966 monograph The Normans in South Wales 1070–1171.29 Brief references to the event appear in David Walker’s 1978 article ‘The coming of the Normans’ and other general works, that touch upon the Welsh revolt of 1094–8, but nothing further is added to the discussion.30 The most recent work to consider the battle, again only briefly, can be found in two articles by David Stephenson. The first concerns the poem ‘Mawl Hywel ap Goronwy’, Hywel being the cousin of Ifor and Gruffudd who were victorious at Aberllech, published in Cambrian Medieval Celtic Studies. He briefly discusses Aberllech and follows J. E. Lloyd in placing it near Ystradgynlais.

It is to be noted that their encounter with the ‘French’ (that is, Anglo-Norman) forces suggests that they were not simply defending the dynastic lands in mid Wales, but had penetrated deep into the south-west part of Brycheiniog, for Aber-llech is located close to Ystradgynlais.31

He goes on to show that some members of the dynasty of Elystan Glodrydd were active in Brycheiniog due to the loss of lands in Buellt.32 Stephenson’s second article published in 2013 entitled ‘Conquerors, Courtiers and Careerists: the struggle for supremacy in Brycheiniog 1093–1282’ also briefly notes the conflict at Aberllech and importantly draws attention to the fact that the Welsh leaders Ifor and Gruffudd were not men of Brycheiniog, but representatives of the dynasty of Rhwng Gwy a Hafren, a territory covering Radnorshire and Builth.33

3.3 Battle Location

The place name Aberllech is comprised of two elements, aber, meaning either the entry of a river into the sea, or a confluence of two rivers, and llech, meaning a stone, more particularly a slab. As the context of the available information makes a coastal site unlikely, the battle is perhaps best looked for at the confluence of two rivers, one of which is called Llech. Two possible sites have been previously suggested for Aber Llech. Theophilus Jones in 1808 suggested it was ‘in Monouthshire’, without elaborating further and J. E. Lloyd in his 1911 book, A History of Wales, suggested it was on the river Llech near Ystradgynlais. A third possibility, not previously suggested, also exists in the Cilieni valley, north of Sennybridge.

Rees, ‘The Medieval Lordship of Brecon’, Transactions of the Honourable Society of Cymmrodorion for 1915-1916, (1917), 165–224. 29 Nelson, Normans in South Wales, p. 91. 30 The minor nature of the event is perhaps best reflected in the lack of reference to it in R. R. Davies seminal Conquest, Coexistence and Change: Wales 1063-1415 (Oxford, 1987), reprinted in paperback as The Age of Conquest 1063–1415 (Oxford, 1991). 31 David Stephenson, ‘Mawl Hywel ap Goronwy: Dating and Context’, Cambrian Medieval Celtic Studies, 57 (2009), 43-4. 32 Ibid, 45. 33 David Stephenson, ‘Conquerors, Courtiers and Careerists: the Struggle for Supremacy in Brycheiniog 1093– 1282’, Brycheiniog, 44 (2013), 30. 11

3.3.1 The River Llech in Pen Rhos, Monmouthshire

Theophilus Jones in his History of the County of Brecknock (1808) makes the following brief reference to the battle of Aberllech. The scattered remains of their forces attempted to reach England, but were intercepted by Griffith and Ivor, the sons of Idnerth ap Cadwgan, at a place called Aberllech in Monmouthshire, where the Welsh again triumphed and satiated their revenge with the blood of their late masters, so that for some time no safety remained for those Normans who continued in the country, but such as their stone walls and castles afforded them34 Jones drew upon Powel’s 1584 work The Historie of Cambria for his basic information and interprets it as meaning that the French were returning eastwards, following events in Brycheiniog, hence the location of Aberllech in Monmouthshire. No further evidence is provided for this statement making an identification difficult, but two possibilities can be suggested. The Lecha is mentioned in the Book Of Llandaf (written c.1135) where it is named as the western boundary of Llan Llwyd35 and Jonathan Coe in his Phd ‘The Place-names in the book of Llandaf’ identifies it with the unnamed stream which runs down the western boundary of Tal y Coed wood and joins the River Trothy, on an obvious direct route between Abergavenny and Monmouth, about one mile east of Llantilio Crosseny (SO 416150).36 This flat area in a shallow valley is the most likely candidate for an identification in Monmouthshire. Another possibility relies upon Bradney who identifies the river Llechau in the same area from a document dated 1576 which names the llecha as the stream that runs ‘from Pen pwll y calch to the Wechan’.37 Penpwll y Calch is at (SO 423135) and a stream runs in a SSW direction before joining Nant Wechan (SO 427128), technically an aber of the river Llech, but it is in a place not seemingly on any useful transport route. 3.3.2 Nant Llech, near Ynyswen, Breconshire

In his brief discussion of the events of 1096 in Breconshire, J. E. Lloyd suggested that Aberllech should be associated with the river known as Nant Llech that joins the Tawe near Ynyswen (SN 833128), to the north of Ystradgynlais. As he freely admits in in his footnote this is an identification based upon the, not unreasonable, inference that the French were returning to Glamorgan from Breconshire.38 Another of Lloyd’s footnotes shows that he based this identification upon the 1898 edition of Theophilus Jones’ History of Brecknock in which Nant Llech is described and includes the line ‘At the Aber of this little river…’39 This would seem to have influenced Lloyd’s suggestion. Due to Lloyd’s work being the standard reference work on medieval Welsh history for most of the twentieth century his suggestion, for that is all that it is, has been repeated many times and become accepted as a ‘fact’, however, there are no earlier references to this identification and no further evidence to support it.

3.3.3 Aber Llech, near Sennybridge, Breconshire

Another possibility, not previously suggested, is a site near the house of Aber Llech in the Cilieni valley, just north of Sennybridge To the south of this house is a site where a stream called Llech Brook, runs down Cwm Llech and meets the river Cilieni (SN 912322), thereby fulfilling the criteria of a confluence of two rivers, one of which is called the Llech.40 If this is the site meant, it begs the question where would Anglo-Norman forces be coming from and going too? One possibility is that the French troops were returning to Brecon having fought to the west, possibly at ’r Fan. This church is recorded in the Book of Llandaf as Lan Guruaet41 and also in a list of churches held by Bishop Joseph42 that Coe dates to the year 1025.43 This gives a plausible reason for French troops to be in the area and the site where the stream that flows down Cwm Llech joins the Cilieni could have been when they were ambushed returning to their stronghold at Brecon.

This area would also seem to make the most sense of the involvement by Gruffudd and Ifor, the sons of Idnerth whom the genealogical texts, discussed in 3.1.4, associate with the area now covered by southern Radnorshire, just over the hills to the north of Llandeilo’r Fan.

3.3.4 Assessment of different sites

The problem remains the interpretation of where the Anglo-Norman troops were returning to and where they started out from. The primary sources provide no details other than they were returning to lands held securely by them from lands still harried by the Welsh and all three identifications above involve three different interpretations. On the balance of evidence the site near Llantilio Croseny seems too far into Anglo-Norman territory, as it was in 1096, for the Welsh to carry easily carry out a successful raid. The Nant Llech near Ynyswen is a possible site, but further evidence of the activities of the Anglo-Normans in Glamorgan at this time would be required to confirm it. Aber Llech north of Sennybridge is another possible site and makes the best sense of the involvement of the sons of Idnerth. However, it must be remembered that the event was a very minor affair and it is unlikely that the site will ever be securely located.

3.4 Archaeology and Historic Terrain Assessment

No medieval finds of archaeological significance have been located near any of the three possible sites following a search of the Portable antiquities scheme database, Archwilio and Coflein. A study of Tithe maps at all three sites has uncovered no evidence and the site at Aber Llech near Sennybridge is also covered by a map drawn in 1793 (NLW 7860) that shows nothing relevant. As the conflict was only a minor ambush, no earthworks or other features are likely to exist that might show up on aerial photographs.

3.5 Historical Significance of the Battle

Following the ambush at Aberllech in 1096 the Anglo-Normans consolidated their conquests in Brycheiniog with further castle building and the chronicles are silent as to any further

40 Aberystwyth NLW 7860 ‘Aberllech from a map of 1793 A. D.’ 41 Evans and Rhys, Book of Llan Dav, p. 154. 42 Ibid, p. 255. 43 Coe ‘Placenames’, p. 429. 13

setbacks. King William returned to Wales in 1097 and reached St Davids, it is likely that open conflict with the Welsh was avoided on this occasion and the Anglo-Normans were pursuing their policy controlling the areas they had conquered by building castles and avoiding open conflict when possible.44 This concentration on ‘positional warfare’ rather than ‘open warfare’ worked well for the Anglo-Normans and by 1100 the valleys and open lands of South Wales were under their control and the Welsh were restricted to the higher ground. Aberllech can be seen as one of the last minor victories by the Welsh, before the Anglo- Normans completed their initial colonisation of the fertile valleys of southern Wales.
