Located at the top of a hill (Figures 3-6), the Kérilien St.P. Av? (48˚37'56.8"N, 04˚19'29.3"W) absolved the double purpose of ensuring the anti-air protection of the Grève and the Dunes de Keremma beach and of directing the fire of the Wn.s and St.Ps

of the close and far defence lines. It was formed by at least two anti-air gun ring emplacements, two bunkers for two groups of soldiers, probably two Regelbau (ruled construction) R622, a R627, indicated also as (Heer―Army) H627, artillery observatory bunker and two other bunkers ( Patrimoine Région Bretagne, 2002b ). The visit took place on 22 May 2016.

The hill was used as free pasturage for livestock. All the bunkers were covered by terrain and vegetation and no longer visible and accessible (Figures 3-6), so that the organization of the St.P. was no longer recognizable. Barely visible, at the top of the hill, covered by hay and encircled by a barrier, was a small, about 5 × 5 m bunker 4. (Figure 5(e)), probably one of said two bunkers. Recognizable on a side of the hill was a rectangular, about 10 × 5 m military shelter, or probably a modern dunghill platform, closed on three sides by walls about 1.5 m high (Figure 5(f)). An aperture, barely recognizable, along the access pathway, on the side of the hill opposed to the platform gave access to the bunker 2., completely covered by vegetation (Figure 5(g), Figure 5(h)). Its interior filled by waste was not accessible, so that it was not possible to determine its type, purpose and internal preservation state. The location and type of the at least two anti-air gun ring emplacements was impossible to be determined.

Only a part of the military staff in service at the St.P. was probably lodged in the two possible R622s, the other part was probably lodged in the nearby farms or in barracks now disappeared.

Notwithstanding the well-developed and diffused German radar technology ( Trenkle , 1979), apparently the Kérilien St.P. was not provided with radar. This absence, in case of bad weather, frequent in Brittany, would let it impossible to direct the fire of the Wn.s and St.P.s from the H627. Thus, the question of the possible radar surveillance of the Grève de Goulven and in general of the coastal defensive sector B, remains open for in-vestigations.

The Rumadiou (Treflez) St.P. Av 59 (48˚37'12.1"N, 04˚14'52.7"W) (Figures 7-12) comprised two bunkers R669, or H669, for captured Russian 76.2 mm FK 39 gun, two open emplacements for 76.2 mm FK 39 gun, two emplacements for 20 mm gun and other minor emplacements. The battery was serviced by the military staff of a hippo-

mobile battery (Patrimoine Région Bretagne, 2002c) (Rapport Pinczon du Sel, 1947-1948a). The St.P. site was included in the terrains of a farm. The R669 are similar to other R669 already encountered in other German artillery batteries (Tomezzoli & Pottier, 2016a) (Tomezzoli & Pottier, 2016b). The visit took place on 22 May 2016.

The R669 2. (Figures 7-9) was located on a side of a dog breeding. Its external concrete structure was in a good preservation state, characterized by a curious ashlar camouflage, typical of the bunker of this area. A wall provided with metallic barrier divided the fire room in two parts: a part was designated for storing agricultural devices and materials; the other for the activities of the dog breeding. All the bunker original furniture disappeared. A water tank was installed in the combat gas extraction system room, the conduits of the system were covered by metal panels and the system pump disappeared. The ammunition room hosted shelves and devices of the dog breeding. The metallic ceiling preserved two joints for the gun lifting.

The R669 3. had a well preserved ashlar camouflaged concrete structure. The interior of the fire room was of difficult access because of the lot of stored agricultural devices and materials. The metallic ceiling preserved two joints for the gun lifting and the grids of the combat gas extraction system. The front fire aperture was walled, probably for preventing the access and for protecting the stored devices.

Both the bunkers were constructed in a rather quiet period by skilled workers, which had time to devote to the completion of the ashlar camouflage. The military staff in service at the battery was probably lodged in a nearby farm and its dependences. However, the necessity of a canteen, lavatories and toilets let think to the existence of some barracks now disappeared. The two open gun emplacements, the emplacements of the 20 mm guns and the other minor emplacements were no longer recognizable.

The Le Veleury―La Metairie (Plouider) St.p. Av 55 (Figures 13-32) (48˚36'9.15"N, 4˚17'59.09"W), indicated also as Grand Kérvélégan St.P., was composed by four bunkers H671 for captured 105 mm French guns K 331, disposed along a country road, five

other bunkers and some machine gun nests. The guns were operated by the military staff of a German horse-drawn battery. The orientation of the guns North―10˚―West allowed the far defence of the Grève de Goulven as well as of the Brignogan-Kerlouan and Dunes de Keremma beaches. On 6 August 1944, to block the progress of the US Army, the battery heavily bombarded the city of Lesneven damaging the city centre, the church and the Saint-François College. The Germans retreated in the night of 7-8 August 1944 towards the Festung Brest evacuating the St.P. after having destroyed the remaining ammunitions stored in the bunkers. The consequent burning destroyed the nearby farm hosting the command post of the St.P (Patrimoine Région Bretagne, 2002d) (Rapport Pinczon du Sel, 1947-1948b) (UNC, 2016). The St.P. site was included in the terrains of a farm. The visit took place on 22/05/2016.

Surprisingly, the H671 1. disappeared, dismantled for unknown reasons. A ground embankment covered the rests of its basement ( Figure 14).

The one room bunker 2. (Figure 15 & Figure 16), about 10 × 5 m, partially buried in the terrain had a well preserved external concrete structure, letting to the vision the imprint of the boards of the original formwork. Although provided with a window, the interior having the internal walls, lacking a thermal insulation system and supports for bunks for the military staff, and the ceiling, lacking the hole of a chimney, suggest that it was not habitable and probably mainly designated for storing only materials, in fact, the ammunitions were stored in rooms inside the H671s (Figure 26(h)). All the bunker

original furniture disappeared and the room was filled with materials. The wooden ceiling provided with metallic supports was intended for preventing the fall of concrete debris in case of projectiles or bombs falling on the coverage. An aperture gave access to the exterior and a niche in one of the wall had unclear purpose.

The H671 3. (Figures 17-20) had a well preserved ashlar camouflaged concrete structure. The relative narrow rear aperture of the fire room and the fixing bolts on the floor of the room (Figure 17, Figure 18 & Figures 19(a)-(d)) suggest that the hosted K 331 gun was detached from its mobile carriage, entered in the fire room through its front aperture and then mounted on a support anchored to said bolts, and that the bunker, as the other H671 of the St.P., had no double fire capability. All the bunker original furniture disappeared and the fire room was empty. For security reasons, a pallet with superimposed stones covered the fixing bolts. On the fire room walls no rests of a thermal insulation system. The fire room and the combat gas extraction system room preserved some rusted portion of conduits (Figures 19(e)-(h)). The metallic ceiling preserved two joints for the gun lifting and the grids of the combat gas extraction system.

The one room bunker 4. (Figures 21-23), few meters away from the H671 3., was similar for shape and dimensions to bunker 2. It was practically completely buried in the terrain, so that it can be supposed that its external concrete structure was well preserved. An inclined concrete ramp allowed accessing its entrance. All the bunker original furniture disappeared and the room was partially filled with materials. The interior

walls preserving possible fixations of a thermal insulation system and the wooden ceiling, provided with metallic supports and preserving a chimney hole, probably for a Festungshofen (fortress oven) WT80 (Figures 22(a)-(d)), suggests that it was habitable. A wall aperture, as that of bunker 2., allowed the access to the exterior and a niche in one of the internal wall, as that of bunker 2., had no clear purpose (Figure 22(a)).

The one room bunker 5. (Figure 23 & Figure 24), about 50 meters away from the H671 3., was similar for shape and dimensions to bunkers 2. and 4. It was completely buried in the terrain, so that, also in this case it can be supposed that its external concrete structure was well preserved. All the bunker original furniture disappeared and the interior was empty. The interior walls, without fixations of a thermal insulation system, and the wooden ceiling, without a chimney hole (Figures 24(a)-(d)), suggest it was not habitable. A wall aperture, as those of bunker 2. and 4., allowed the access to the exterior and a niche in one of the internal wall, as that of bunkers 2. and 4., had an unclear purpose (Figure 22(a)).

A further one room bunker, buried in the terrain, similar to bunkers 2., 4. and 5. was about 30 meters away from bunker 5, but, covered by vegetation and terrain, it was not accessible.

The H671 6. (Figures 25-28) was covered by a clump of vegetation which partially masked its ashlar camouflaged concrete structure (Figure 25). All the bunker original

furniture disappeared. The fire room was empty, but the terrain covering its floor masked the fixing bolts of the support of its K 331 gun. On the fire room walls no rests of a thermal insulation system. The fire room and the combat gas extraction system room preserved some rusted portion of conduits (Figures 26(e)-(g)). The metallic ceiling preserved two joints for the gun lifting and the grids of the combat gas extraction system.

The H671 7. (Figures 29-31) was also covered by a clump of vegetation which partially masked its ashlar camouflaged concrete structure (Figure 29). All the bunker original furniture disappeared. The fire room was empty, but, also in this case, the terrain covering its floor masked the fixing bolts of the support of its K 331 gun. On the fire room walls no rests of a thermal insulation system. The fire room and the combat gas extraction system room preserved some rusted portion of conduits (Figures 30(d)-(f)). The metallic ceiling preserved two joints for the gun lifting and the grids of the combat gas extraction system.

No trace was appreciable on the terrain of the two buried bunkers 8 (Figure 32).

The owner of the St.P. site did not commented about the reasons of the dismantlement of the H671 1. However, he confirmed that the command post of the St.P was hosted in the nearby farm and that military staff in service at the St.P. was lodged in the farm dependences. However, the necessity of a canteen, lavatories and toilets, also in this case, suggest the existence of some barracks now disappeared.

No traces were visible on the H671s, the one room bunkers, the nearby farm and the farm dependencies of said ammunitions destruction and consequent burning.

The Kerbreslauen St.p. Av 82 “Unstrut” (German river tributary of the Saale) (Figures 33-42) (48˚39'00.5"N, 04˚20'08.9"W), indicated also as Grand Kérvélégan St.p., was composed by four bunkers H669 for captured Russian 76.2 mm FK 39, disposed along an arc of circle, two other bunkers disposed behind the H669s and probably by some machine gun nests. The guns were operated by the military staff of a German horse-drawn battery, probably the same that operated the St.P Av 55 (Patrimoine Région Bretagne, 2002e). The St.P. was probably evacuated in the same night of 7-8 August 1944 as the other St.P.s around the Grève de Goulven during the retreat of the Germans towards the Festung Brest. The St.P. site was included in the terrains of a farm. The visit took place on 22/05/2016.

The R669 1. (Figure 34 & Figure 35) had the rear side aperture of the fire room covered by the vegetation, letting visible only on the front side a well preserved ashlar camouflaged concrete structure. The fire room was difficult to access because of the lot of cut wooden logs obstructing the front aperture. The metallic ceiling preserved two joints for the gun lifting and the grids of the combat gas extraction system. On a fire room wall was an original inscription: Sperrfeuer “Unstrut” u.Gr.R. 76 mg 7200 2 Kampfsätze in 2.Min. = 12 Schuß translatable as: fire barrage “Unstrut” under Group Regiment, 76 machine guns, 7200, two combat set in two minutes = 12 shots. The inscription, surviving an evident attempt of erasing, is interesting because the term 76 mg, i.e. machine guns, permits of estimating at about 100 the number of soldier and officers composing the military staff of the St.P. The term 7200 informs about the consistence of the ammunition, letting in doubt if it refers to the total ammunition of the machine guns or of the 76.2 mm guns. The term 2 Kampfsätze in 2.Min. = 12 Schuß defines the nominal fire power of the guns as two combat set in two minutes equivalent to 12 shots.

The R669 2. (Figure 36 & Figure 37) was covered by the vegetation, which here and there let visible the preserved ashlar camouflaged concrete structure (Figure 36). The fire room was empty, only a lot of stones partially obstructed its rear aperture, terrain covering the floor masked the rails of the vibration dampening system. The metallic ceiling preserved two joints for the gun lifting and the grids of the combat gas extraction system. The fire room and the combat gas extraction system room preserved some rusted portion of conduits. The ammunition room was cluttered with market cassettes. On a fire room wall was the original inscription, similar to that of H669 1.: Sperrfeuer "Unstrut" u. Gr.R. 76 mg 7450 Kampfsätze translatable as: fire barrage “Unstrut” under Group Regiment, 76 machine guns, combat sets, which, although incompletely, reproduced the information of the H669 1. inscription.

The R669 3. (Figure 38 & Figure 39) was covered by the vegetation, which here and there let visible a well preserved ashlar camouflaged concrete structure. The fire room was empty but terrain covering the floor masked the rails of the vibration dampening system. The metallic ceiling preserved two joints for the gun lifting and the air intakes of the combat gas extraction system. The fire room and the combat gas extraction system room preserved some rusted portion of conduits. On a fire room wall was the

original inscription: Sperrfeuer “Unstr u.Gr.R. 7 mg 74 2. Kampfsätze in 2 Min.”, which, although incompletely, also in this case, reproduced the information of the H669 1. inscription.

The R669 4. (Figures 40-42) appeared isolated in a wheat field. It was little covered by the vegetation, so that its well preserved ashlar camouflage of its concrete structure was completely visible. The fire room was empty but terrain covering the floor masked the rails of the vibration dampening system. The metallic ceiling preserved two joints for the gun lifting and the air intakes of the combat gas extraction system. The fire

room at the floor level and at the ceiling level and the combat gas extraction system room preserved portion of the conduits of the system. The combat gas extraction system room and the ammunition room were empty. On a fire room wall the original inscription at the limit of the readability: Sperrfeuer “Unstrut” u.Gr.R. 75 mg 74 2. Kampfsätze in 2.Min which, although incompletely, also in this case, reproduced the information of the H669 1. inscription.

The owner of the St.P. site informed, probably referring to the after war, that no gun

was installed in the bunkers. He indicated the emplacement of the bunker 5. which was buried in the terrain and its entrance covered by the vegetation and declared that two rooms were inside it, which suggests that it was a R622 (Figure 5(i)) for two groups of six soldiers. He confirmed that German soldiers lived in the dependencies of the farm. However, the necessity of a canteen, lavatories and toilets suggests also the existence of some barracks now disappeared. He added that the farm (Figure 43) was seat of a Kommandantur, probably the command post of the St.P., which hosted also prisoners' cells at the first floor and in the granary, and that the bunker 6. was buried in the terrain and no longer accessible.

The Bréhichen St.P Av? was located halfway between Plounévez-Lochrist and the hamlet of Lochrist. It comprised four platforms for 105 mm gun, which were only roughly cut in the terrain at the time of the Liberation (Rapport Pinczon du Sel, 1947-1948c). This vague indication has not located precisely position of this St.P. and, consequently, it was not possible to organize a visit.
