The
Royan Pocket, April
1945
Historic background
My
attention was drawn to this interesting late war sideshow campaign by
an odd photo which popped up on a French modeling group I follow of
Facebook. The photo (below) was of a Somua S-35 accompanied by French
soldiers in 1940 era kit, yet titled April 1945! It turns out The
Free French had gathered up any repairable and reusable 1940 tanks
they could find as the Allies advanced through France and built these
into fighting units to use against the isolated German pockets left
behind along the coast of France! Being a pack rat for knowledge
about unusual french units and liking the idea of having my Somua
back on the tabletop I did some digging, what follows is brief
article/background based on some weeks of internet research.
Please check out my earlier piece on 13e Régiment de Dragoons 1944/45 for background info on this interesting unit.

Historic background
With
the somewhat chaotic collapse in the west during the summer of 1944,
Hitler created a strategy to hold fortified "Atlantic pockets"
as diversions and potential bargaining chips, isolated German
garrisons were ordered to dig in along the coast, including in the
Gironde estuary region around Royan.
In
early September 1944, Forces Françaises de l'Intérieur (FFI)
maquisards from Charente, Dordogne, and other regions, coordinated
under Colonel Henri Adeline's command from September 6, intensified
their operations to encircle remaining German strongholds. On
September 12, 1944, FFI forces occupied Rochefort, cutting the vital
land connection between the German garrisons at La Rochelle and
Royan, thereby formally enclosing the Royan Pocket. This isolation
encompassed the town of Royan, the Arvert Peninsula, the southern
part of Oléron Island, and the northern Gironde estuary approaches,
trapping approximately 20,000 German troops in a defensive perimeter
fortified since 1942 as part of the Atlantic Wall.
The
initial German defensive setup in the pocket was commanded by Oberst
Hartwig von Pohlmann, who had taken charge of Festung Gironde Nord on
June 1, 1944, with his command post at Villa Le Lys Rouge in Royan.
Pohlmann immediately declared a state of siege following the
conection
to
Rochefort being
cut!
The
area was organised in multiple lines of concrete bunkers, artillery
batteries, including four 240mm/50
Modèle 1902 guns (with a range of 18 miles)
taken off the old Danton class semi-dreadnought Condorcet following
the scuttling of the French fleet at Toulon in late November 1942 at Batterie Gironde, minefields, and
anti-tank positions to repel land assaults while also relying on the
estuary's geography for protection. Supply challenges mounted rapidly
due to Allied control of surrounding areas; the Germans maintained
limited maritime contacts via blockade runners to the nearby Pointe
de Grave fortress and occasional links to La Rochelle, supplemented
from late October 1944 by nighttime air drops from Germany for
essentials like medicine and mail, alongside local foraging and
pre-stocked rations intended to sustain the garrison for up to six
months.
Geography,
Defenses and
Terrain
Layout
The
Royan pocket encompassed a coastal enclave in southwestern France,
centered on the town of Royan and extending across the eastern shore
of the Gironde estuary. It included the Arvert peninsula to the south
along the mainland, while the western boundary was formed by the
Atlantic Ocean. The pocket was designated as Festung Gironde Nord,
distinct from but defensively coordinated with the separate Festung
Gironde Süd across the estuary (from Pointe de Grave northward).
This divided layout focused on the northern sector, spanning coastal
areas from Ronce-les-Bains in the north to Pointe de Suzac in the
south, with the Gironde estuary itself serving as a formidable
natural barrier, up to 5 kilometers wide in places, with navigable
channels guarded by the rocky plateau of Cordouan, both
isolating
the pocket from inland advances and complicating amphibious
operations. The terrain featured a mix of sandy beaches and exposed
coastal stretches, and the rugged Côte Sauvage south of Pointe de
la Coubre, which provided potential landing sites but were backed by
dunes and low cliffs. Inland, dense forests like the Coubre forest
dominated the northern sector, offering natural cover and difficult
access through thick pine woodlands extending to Pointe de Suzac.
Marshes and wetlands, particularly along the Seudre river to the
east, acted as additional obstacles, flooding seasonally and
channeling any ground movements into narrow, defensible corridors.
Oléron Island, to the south, provided flanking artillery support but
was a separate German-held position only
connected to Rayon via radio and the occasional
blockade runner.The overall northern sector covered roughly 150-200
square kilometers.
German
Fortifications
The
German fortifications in the Royan pocket formed an integral
extension of the Atlantic Wall, designed to create an impregnable
fortress capable of withstanding prolonged sieges and blocking access
to the Gironde estuary. Construction began in August 1942 under the
direction of the 2nd Fortress Pioneer Staff and the Organisation
Todt, utilizing forced labor from German volunteers, Spanish
prisoners and French workers to erect a network of concrete bunkers,
casemates, and armored cloches along the coastline from
Ronce-les-Bains to the Pointe de Suzac. These defenses were organized
into three concentric lines: the coastal front with 43 support points
featuring heavy batteries; an inner line around Vaux-sur-Mer, Royan,
and Saint-Georges-de-Didonne with 135 light support points including
trenches, machine-gun nests, and four Panzerwerke (Pzw I–IV)
blocking key roads with anti-tank guns and mortars; and a rear line
from Chaillevette to Taupignac, securing the Coubre forest with
points 200–235.
The
pocket held approximately 12,000-15,000 troops in the northern sector
by late 1944, coordinated with 3,500 in the southern Gironde Süd.
Artillery emplacements were a cornerstone of these defenses, with the
Marine Artillerie Abteilung 284 and Heeres Küsten Artillerie
Abteilung 282 deploying batteries ranging from 75 mm to 240 mm guns.
Notable examples include the Batterie Gironde in the Coubre forest,
armed with two 240 mm guns in armored turrets (range 27 km); the
Batterie Cordouan at Pointe de Coubre with four 150 mm Krupp guns;
and the Batterie Hindenburg at Fort du Chay, protecting Royan harbor
with 75 mm and 76.2 mm casemated guns plus Flak units. Minefields
were extensively laid along the forward lines and around support
points, complemented by anti-tank obstacles such as dragon's teeth,
barbed wire, stakes, and remote-controlled Goliath explosive charges,
with Panzerwerke like Pzw III at Belmont featuring rotating armored
cloches for all-around fire.
The
Coubre forest served as a key rearward bastion, manned by the Tirpitz
Battalion, comprising of some 800 sailors from ships sunk in the
Gironde in August 1944 and fortified with all around defenses, radar
stations, Tobruk turrets, and 50 machine-gun positions around its
batteries. Royan city itself was heavily defended as the pocket's
core, with urban bunkers, Flak towers camouflaged as houses and port
defenses at Le Chay, housing approximately 5,500 troops across
infantry, coastal artillery, and naval units under Konteradmiral Hans
Michahelles by late 1944.
Logistical
adaptations enabled sustained resistance despite encirclement,
including ammunition and command bunkers for operational autonomy, as
well as underground storage facilities within larger complexes like
the Triloterie command post. Resupply was limited after September
1944, relying initially on sporadic sea runs from La Rochelle's
U-boat base and blockade runners until early 1945, when Allied
interdiction curtailed such efforts.
Opposing
Forces
Allied
Command and Units
The
Allied effort to reduce the Royan pocket was directed by General
Édgard de Larminat, commander of the French Forces of the West
(Forces Françaises de l'Ouest, or FFO), which were established in
October 1944 specifically to eliminate the remaining German Atlantic
pockets. Under Larminat's oversight, the operation integrated
French ground, naval, and air elements with limited American support,
emphasizing coordinated multinational action to isolate and capture
the German garrison. Key subordinates included Colonel Henri Adeline,
who commanded the Royan sector and elements of the 10th Infantry
Division, drawing on his prior experience leading French Forces of
the Interior (FFI) in southwestern France. Colonel Jean de
Milleret oversaw the assault on the Pointe de Grave sector,
coordinating amphibious and ground advances across the Gironde
estuary. The primary ground forces comprised approximately 30,000
French troops for the operation, organized into several divisions and
irregular units, including colonial battalions and FFI former
marquis.
The
10th Infantry Division, was
formed
largely from FFI resistants and regional recruits, provided infantry
support for operations around Royan, focusing on clearing fortified
positions. The 23rd Infantry Division, including the 50th and
158th Infantry Regiments, formed the core assault force in the
Division
de Marche
Gironde, advancing through mined terrain and blockhouses. Elements
of the French 2nd Armored Division (2Dble), equipped with american armour - Sherman
tanks, M10 tank destroyers, etc and other
independent French
armoured
formations
(see notes below) supported
the infantry.
FFI
irregulars, organized into groupements such as Z, RAC, and Roland
from the Armée Secrète, supplemented regular units with local
intelligence and guerrilla actions. American contributions
included elements of the 66th Infantry Division for containment
duties in adjacent sectors and aerial support from the 447th Bomb
Group of the US Army Air Forces, which conducted precision strikes on
German defenses. Naval operations were led by Vice Admiral Joseph
Rue, who commanded a fleet of ten Allied warships providing offshore
bombardment to soften German coastal batteries ahead of the ground
assault.
German
Command and Units
The
German forces in the Royan pocket operated under the broader command
of the Atlantic Army Detachment, responsible for the remaining
Atlantic coastal strongholds after the main German withdrawal from
France in August 1944. Local command in Royan was held by Colonel
Hartwig Pohlmann, while Rear Admiral Hans Michahelles oversaw the
overall pocket, including coordination with adjacent positions like
the Pointe de Grave. Troop strength in the Royan pocket totaled
approximately 8,000–9,000 men across the isolated enclave, with
around 5,500 concentrated in the Royan area itself; this included a
mix of Wehrmacht infantry, Kriegsmarine sailors (such as elements of
the Tirpitz Battalion), artillery crews, and forcibly enlisted
foreign personnel from countries like Poland, Hungary, Romania, and
others. Encircled since September 1944 following the Allied advance,
the German garrison adopted a static defensive posture with minimal
reinforcements possible due to the naval blockade and air superiority
of Allied forces. Supplies were initially stockpiled for prolonged
resistance, including food reserves sufficient for months and ample
weaponry, but isolation led to deteriorating conditions, with
resupply attempts limited to occasional night flights or neutral
shipping that were largely intercepted. Morale among the defenders, a
blend of regular army and naval units, was strained by the siege but
sustained through fortified positions until the final assaults in
April 1945.
Preparation
Whilst
the plan to retake the pocket was formulated as early as September
1944, the gathering and organising of some 65,000 former member of
the FFI delayed preparation, then came the german counter offensives
in the Ardennes and Colmar during the winter of 1944/45 and the
operation was postponed. A new plan “Operation Vénérable” was
developed for spring 1945. The plan called for French forces to take
the pocket supported by allied air forces and naval support. The
French former resistance fighters spend months in intelligence
gathering, conducting patrols, ambushes, and reconnaissance raids
from autumn 1944 to map German positions, including details on
minefields and gun emplacements often obtained through captured
documents and local networks.
Finally
From early January both British and US tactical bomber units began
systematic high intensity raids against both the city and its
defenses and emplacements. On the night of January 4-5 RAF bomber
command dropped 1,576 tonnes of high explosives onto the city! But
due to poor conditions no ground offensive was possible, but the
build up continued. In April over the nights 14-15, 1,000 bombers of
the US Eighth Air Force dropped 2,551 tonnes of conventional
ordinance as well as clusters of 85 gallon Napalm canisters onto the
city and its defenses (this being the first recorded combat use of
Napalm in NWE). These airstrikes were supported and coordinated with French
ground forces who focused on demolishing concrete bunkers and
artillery emplacements in the Festung Gironde Mündung Nord.
Complementing the air campaign, Free French naval forces under French Vice-Admiral
Joseph Rue also took part in the battle. The admiral had a fleet of 10 warships centered around the battleship Lorraine along with the heavy
cruiser Duquesne, destroyers Alcyon,
Basque and Fortuné, destroyer
escort Hova, frigates Aventure,
Decouverte and Surprise, and sloop
Amiral Mouchez. The fleet conducted heavy shore bombardment starting on April 15,
1945, firing a total of 27,000 artillery shells (Lorraine alone fired
236 x 13.4 inch shells, 192 x 5.5 inch shells and 538 x 75mm shells) over five days
at German positions around Royan and the Gironde estuary mouth.
The Battleship Lorraine
Ground
Operations and Surrender
The
ground phase of Operation Vénérable commenced on 14 April 1945,
following intensive aerial and naval bombardments that softened
German defenses in the Royan pocket. Under the overall command of
Général de Division Edgard de Larminat, the assault was primarily
executed by French forces of the 10ème Division de Marche
d'Infanterie (10th Infantry Division), reinforced by elements of the
2ème Division Blindée (2Dble), including tank units
from the 12ème Régiment de Cuirassiers and tank destroyers from the
Régiment Blindé de Fusiliers-Marins. These troops advanced from
positions near Le Chay and Médis, targeting the German outpost line
along the Arvert Peninsula to establish a base for the main push into
Royan. Supported by artillery barrages and close air support from
Allied aviation, the initial advances captured forward positions such
as Semussac and Trignac, with reconnaissance patrols identifying
heavily fortified strongpoints equipped with mines, barbed wire,
blockhouses, and anti-tank guns. On 15 April, the main infantry
assault intensified, with battalions like the Bataillon de Marche n°2
(BM 2) breaching minefields at objectives codenamed B.1 (Boube), B.2
(La Grange/Brandes), and B.3 (Moulins-de-Didonne) near Didonne.
Accompanied by B1 bis tanks of 2/13e Régiment de Dragoons and Bren carriers, French voltigeur
companies overran these positions in close-quarters fighting,
capturing over 100 German prisoners and neutralizing blockhouses
while advancing several kilometers toward Royan. Further engagements
occurred in the Coubre forest area, where Allied troops clashed with
the German ailors
from the Tirpitz
battalion manning bunkers, resulting in heavy combat amid dense
terrain that favored defenders. By evening, French forces from the
4ème Régiment de Zouaves and BM 2 reached the suburbs of Royan,
linking up with armored elements and securing La Triloterie after
destroying fortified casemates armed with 88mm guns. These actions
pierced the main German lines, though they came at a cost, with BM 2
alone suffering 23 killed and 84 wounded in the day's fighting. The
following day, 16 April, French units conducted cleanup operations
east of the Royan road and along the coastal marsh, capturing
additional prisoners and clearing minefields while establishing
defensive positions facing the city center. By 17 April, the German
commander, Konteradmiral Hans Michahelles, capitulated in Royan,
yielding approximately 8,000 prisoners from the pocket's garrison.
Remaining
resistance at Pointe de Grave, across the Gironde estuary, was
assaulted on 20 April by troops under Général de Division Robert de
Milleret, who overran the fortified peninsula after coordinated
artillery and infantry advances, securing the southern flank.
One of the Somua being unloaded at Île d'Oléron
The
pocket was fully cleared by late April, with the amphibious assault
on Île d'Oléron, codenamed “Operation Jupiter III” was launched on 30-31 April by French commando and marine units, supported by ample offshore naval gunfire and air support. The island was taken against some opposition from its 2,000+ defenders; two Somua S-35s from 13e RD were ferried over to the island to assist the marines and commandos in their task. This completed
the reduction of the Royan enclave just days before VE Day on 8 May
1945, allowing the cancellation of the planned assault on nearby La
Rochelle under “Operation Mousquetaire”.
Afterword
Casualties and Destruction
The Royan pocket campaign resulted in
significant human and material losses for all parties involved.
Allied forces suffered 346 killed, 1,501 wounded, and 32 missing
during the ground assault from April 13 to 20, 1945. German
defenders, numbering around 5,500 in the core Royan sector of the
pocket, incurred heavy casualties, alongside the capture of 8,400
prisoners by the campaign's end on April 20. Civilian casualties were
particularly devastating, as approximately 3,500 French residents
remained in German-held areas, with 1,500 killed primarily during the
Allied aerial bombardments. Material destruction was near-total in
Royan, where heavy bombing by RAF and USAAF aircraft, totaling over
6,800 tons of ordnance, including napalm, razed more than 90% of the
city, burning 500 houses and reducing public monuments like
Notre-Dame Church to ruins.
French military leaders insisted on a forceful assault over awaiting
the pocket's inevitable surrender, prioritizing a symbolic national
liberation to bolster post-war prestige, despite the evident risks to
civilians and infrastructure in the largely evacuated resort
town. In its legacy, the Royan pocket stands as a poignant symbol
of France's broader liberation, highlighting the pivotal role of
reconstituted French units like the Forces Françaises de l'Intérieur
(FFI) and armored divisions in reclaiming sovereignty from Nazi
holdouts.
This era also illuminated overlooked civilian ordeals, with thousands
enduring the raids' terror, while unit-specific contributions, such
as Leclerc's tanks breaching defenses, affirmed the French Army's
integral place in the Allied victory narrative.
My Game
After researching this fascinating piece of history I felt compelled to create some sort of tabeltop game losely based on the fighting around Royan.
This is a composite game based on my reading of the units combat reports, I have taken some liberties with the German organisation.
Silencing
the Battery at Les Huttes
Following
the capture of Royan and the surrender of Admiral Michahelles,
the French then turned their attention to the south side of the
Gironde Estuary. The Germans had fortified this side in a similar way
to the Royan (North) bank, and their batteries and forts still
effectively close the estuary to traffic. 1st Squadron of the 13th
Dragoons were taken by train to Grayan and then attached to the
infantry units assigned to clearing the southern shore of the estuary
right up to Pointe de Grave. The advance started on 18 April and the
French met some solid and determined defence, from a desperate enemy,
isolated and alone, but with ample ammunition in well prepared
positions!
By
19 April the French had broken through the outer line, but now found
themselves facing two battery strong-points one each side of the
isthmus – Les Huttes and Arros! These two well positioned forts not
only could fire out to sea (Arros) or bring fire on vessels in the
estuary (Les Huttes), but effectively prevented access to Pointe de
Grave as they sat either side of the only road up the isthmus.
The
Scenario
1/13e
RD are tasked to support 13th & 14th Companies of
Lieutenant-Colonel Durand`s 131st Infantry Regiment in their assault
on the German battery at Les Huttes (commanded by Oberleutnant
MA Helmut-Horst Molle).
The
battery is concealed from the sea in a defilade position within the
sand dunes and scrub of the peninsula. There is also a concrete
command control bunker, and anti-aircraft defences. On the landward
side the battery is protected by mine-fields, wire and MG positions.

The
game
The
Germans deployed as per their game organisation whilst the French
decided to commit 13 Company along with a squadron of Somua, an
engineers platoon and the AT platoon straight up the road; whilst 14
company (again with a Somua squadron and engineer platoon) would
advance up the right side of the table and once through the line of
dragons teeth this force would advance up beach side of the isthmus
headed straight for the battery. Both engineers platoons are tasked
to clear mines and blast holes in the lines of anti-tank obstacles
and wire, it is the job the of Somua squadrons of 13e RD to provide
direct support and suppress German positions. The French company HQs
can also call support fire from battalion mortars (including smoke)
and the US FAC can call on close air support also.
Turns
1 & 2 the French advance under sporadic mortar fire, the 14 Company HQ manages to contact their attached mortars, but 13 Company and the FAC radios fail!
Those with keen eyes will notice the lead Somua has both German markings and a German commander 😁
Turn
3 both flanking platoons (left and right) are hit by long range MMG
from German bunkers, both platoons take casualties. 14 Coy (on the
right) call down smoke to mask their men.
Turn
4 Whilst 13e RD Somuas target spotted bunkers (ineffective), the
French infantry spread out and continue their advance, they do
exchange fire with some dug-in Germans, both sides take casualties.
The lead Somua on the road hits a mine!
This
does alert the French to the presence of minefields and their
engineers get to work trying to find and clear paths. 13 Coy still
has problems with its radio, but the US FAC finally calls in TAC Air
support!
Turn
5 the French engineers begin clearing lanes through the minefields.
The
surviving Somuas continue to try and suppress the bunkers (still
ineffective). The French infantry continue to take casualties from MG
fire and dug-in Germans, and mortar fire.
14
Coy once again calls down smoke to mask their troops advance.
A
P47 arrives over the table is is directed against the bunker on the
French left.
The
French decide to deploy their Pak40 against the bunker on the right.
Turn
6 on the right French infantry stumble into more unmarked mines!
But
the Pak40 is bang on target and suppresses the Bunker with its first
shot
On
the left the P47 dives and unloads all over the bunker, it and its
occupants are wiped out!
In
the center the engineers have most cleared their paths, but take
casualties from LMG and mortar fire!
Turn
8 The Pak40 lays another round into the bunker on the right, this
time totally destroying it!
The
French engineers start laying charges to blow gaps in the dragons
teeth and roadblock!
On
the far left and right, French infantry have worked their way around
the edges of the minefields and pushed through the wire and dragons
teeth. They still come under sporadic fire, but respond with their
own LMGs and rifle grenades plus 80mm mortars.
A
rifle grenade takes out this LMG nest
Turn
9 the engineers work continues only hampered by the odd 81mm mortar
bomb. The infantry continue their advance, slowly gaining the upper
hand against the remaining German defenders. The Pak40 limbers up and
the FAC climbs aboard his jeep to move closer to the action.
Turn
10 the charges clear gaps in the dragons teeth and blast a hole
through the road block
On
the left and right the French infantry advance virtually unopposed
Turn
11 The German 50mm emplacement spots and fires on the lead Somua
(miss), the french engineers burn out the last LMG nest covering the
road.
Turn
12 the German 50mm has another go at the Somua this time hitting, but
the Somua`s 47mm of frontal armour shrugs it off! The Somua replies
and wipes out the German gun!!
Elsewhere
across the table the French infantry and engineers advance virtually
unopposed.
Turn
13 the French advance across the entire table front

14 Both French company HQs and the US FAC can all now see both the command
& control bunker and the artillery battery! The French infantry
and tank halt, and artillery, mortars and TAC Air are called down
with a vengeance upon the Germans!!
Over
the next 6 turns 81mm mortars, 105mm artillery and strafing and
bombing runs by P47s and P38s effectively end the game!! One P47 is
shot down, but I consider that a small price to pay in the long run.
Command bunker after much punishment!
Remaining sailors flee past the burning ammunition dump
Battery well and truly destroyed
Even the isolated observation bunker gets wasted!
The
one unlucky P47
An interesting visual game to try and create, with a nice mix of figures and kit.
