  • Op. Narwhal - OKW - German Invasion of Britain

    This is the thread for the German team in the Operation Narwhal game. It is 'out of bounds' to players from the other team, but it might be an idea to set up a social group for any detailed planning, just in case...

    Here is the Invasion Planning briefing:

    Invasion Planning briefing.


    Choice of theatre.
    There are many plausible invasion areas along the South and East coasts of England. On the screenshots, the blue blobs with anchors in are "anchorage" hexes to which amphibious assault is allowed.

    The initial invasion force consists of up to 8 Infantry divisions, plus 4 Amphibious Panzer battalions and the airborne troops (up to 4 Parachute and 3 Airlanding Regiments).

    Not all 8 divisions need be employed on the first day, some can be scheduled to arrive on turn 2 or turn 3. Indeed, unless you are attacking on a very long frontage, not all 8 divisions will fit onto the invasion beaches on Day 1 - and such an attack is not necessarily advisable.

    OKW should consider which of the following areas are preferably for the initial attack.

    Map 1: South East England:



    1) Kent. An attack into East Kent at Folkestone, Ramsgate or Dover has the virtue of being very close to the occupied Channel ports and airfields. Dover is also a major port which will be of great value to subsequent action (and can be expected to be well-defended). The disadvantage of Kent is that it forms a peninsula, the south side of which is made up of the inaccessible Romney Marsh. There is a risk that troops in East Kent would be bottled up with only a two-hex frontage to attack on.

    2) Sussex. The coastline from Hastings to Shoreham is also close to the Channel ports and largely consists of shingle beaches (the exception is one hex filled by the cliffs of the South Downs, W of Eastbourne) The only significant port on this stretch of coastline is Newhaven. The Sussex coast is very open and potentially vulnerable to attack from three directions: from the W (via Portsmouth), NW (via Crawley) and N (via Sevenoaks). However, it also provides a base of operations against all of those objectives
    .

    Map 2: SW England


    3) Hampshire. Portsmouth and Southampton are both major ports and Portsmouth is a major naval base. Attempting an amphibious landing onto one or both of these areas would be possible but very difficult as this area is inevitably heavily patrolled by the Royal Navy and strongly garrisoned. Success would risk a counter-attack on both flanks.

    4) The West. It would be possible to launch attacks on Dorset, Devon or even Cornwall. The ports at Plymouth or Portland could be used, at a stretch, to support an invasion. However, this risks creating a very long sea supply line and a long distance for air support. The Army would be ashore a very long distance from its objectives. Expect RN patrols in the vicinity of their naval bases, which would need to be dealt with.

    Map 3: East Anglia


    5) East Anglia. There are beaches in the vicinity of Great Yarmouth and Ipswich that could support an invasion, and the port of Harwich (Ipswich) could be used as a supply base. These beaches are the closest to Germany, but attacking here does place the Royal Navy bases in the Thames Estuary between most units from France and the invasion theatre. If the British are deployed to protect London from an invasion in Kent and Sussex, then landing here will wrongfoot them. However, the road an rail network in East Anglia is sparser than in the South East, perhaps slowing down an advance.

    Heer (Army) Briefing

    This is a detailed briefing for the Heer - also relevant to other arms.

    Order of Battle:

    Units from 6, 9 and 16. Armees comprising:
    * 18 x Infantry Division - 17,000 men lavishly equipped with machine guns, AT guns, and mortars. Integral artillery support includes 105mm and 75mm howitzers and a small number of 150mm infantry guns.
    * 2x Mountain Infantry Division - somewhat more likely equipped than Infantry Divisions.
    * 7th Flieger Division: 4x Parachute regiment, 3x glider regiment. Regiments are stronger than regular infantry regiments and more capable of independent operations. (NB these formations are under Luftwaffe control until they land in England).
    * 4x Panzer division, 2x motorized division, 2 independent motorised brigades.
    Panzer divisions have a tank strength of 120 tanks, a mixture of Pz III, Pz IV,Pz II and Pz 38t plus a strong motorised infantry component. Motorized troops have a much lower rifle strength than a leg infantry division, but heavier integral support, including a small number of Sturmgeschutz. On the whole a motorised infantry division is a little less effective than a leg division.
    * 4x independent Amphibious Panzer battalion - each has a strength of 80 amphibious tanks and should be used to support the initial attacks. They have no infantry component.
    * 3x Army HQ formation - these are rear-area units which can improve supply to nearby units, and also conduct engineering tasks like rail repair.
    * 12x Corps HQ formation - Corps HQs have two regiments of 150mm artillery. They also have the same supply effects as Army HQs but have no engineering ability.

    Intelligence.
    In England there are approximately 15 Infantry and 2 Armoured divisions and apparently a number of independent brigades.

    British Infantry divisions are smaller than German divisions and have fewer machine-guns and AT guns, but they have a larger complement of artillery. According to their TOEs, all British divisions are motorised. Many British Army units are short of equipment, which we are still recovering from the beaches at Dunkirk.

    The British Armoured divisions are equipped with a mixture of "Matilda" heavy tanks, "Cruiser" and "Light" light tanks. The "Matilda" is formidable but the lighter tanks are less effective than our Pz II.

    The British Army is reinforced by a "Home Guard" militia force. The strength and effectiveness of this force is unknown.

    Reports suggest that the enemy's divisions are distributed around the coast to control a long area of coastline, with a substantial central reserve. It is not know how quickly the British will be able to concentrate troops against the invasion.

    Mission.

    The mission of the German Army is to land in England, establish a beachhead, defeat the British army and conquer the country.

    The plan for the invasion is of crucial importance. See separate briefing about invasion transport an logistics. However OKH should also give some thought to subsequent strategy. There are not enough troops available to fight all the way up England attritionally. It will be necessary to encircle and destroy a substantial part of the British army. OKH should give some thought to such an operation. OKH also need to consider whether London, which is the main operational obstacle as well as the major objective, will be captured directly, or bypassed.

        Invasion Logistics briefing

        Transport and supply are immense challenges for this operation. Much of this is handled by manual bookkeeping, because TOAW3 isn't quite up to it. This briefing tells you want to know how this is handle behind the scenes let me know.


        Transporting the Army across

        The invasion will rely heavily on improvised transport. These converted barges, trawlers and so on are very slow and vulnerable. Priority transport is not only limited by the shipping available but by the space on the landing beaches.

        A certain amount of 'priority' transport which does not suffer these hindrances will become available once the Army has secured a large enough port.

        The game is divided into "phases" for the sake of transport capacity. The number of divisions of transport available depends on which phase you are in.

        Phase starting - number of Divs of improvised transport
        T+0 / Turn 1... 8 divisions
        T+3 / Turn 4 ... 4 divisions
        T+6/ Turn 7 ... 4 divisions
        T+9/ Turn 10 ... 3 divisions
        T+12/ Turn 13 ... 2 divisions
        T+19 / Turn 20 ... 2 divisions
        Each subsequent week (7 days) ... 3 divisions.

        For these purposes, Panzer and motorised divisions have twice the weight of an infantry division. HQ units have half the weight of an infantry division.
        Also bear in mind that the amount of space to unload on beachheads is limited: each anchorage hex can only receive one regiment per turn.

        If at the start of a phase the German army has taken one or more of the "major ports" then the German team gets an extra division worth of transport capacity per phase, which isn't restricted by the improvised transport special rules. This transport can only go to a major port. But acquiring more than one major port doesn't mean you get any additional transport capacity.
        So on turn 20 you can have a total of 28 divisions transported to England, plus the parachute force. In reality fewer divisions will be shipped but also a number of HQs.

        OKW needs to determine priorities for shipping ofor the initial invasion and the subsequent reinfocement of the beach-hea.

        Supply.

        Supplying units in England depends on retaining control of the sea along which supply can move. In game terms this means the German navy needs to occupy one or more of the hexes immediately off the English coast marked as German supply points. On the start of any turn where this is the case, that hex will act as a supply centre for German units. That means supply will be traced along any functioning railroads at full value, then along roads and across other hexes at a lower value.

        Units have a supply value representing their stocks of fuel and ammunition, so losing supply for a turn or two is not necessarily a disaster - but long period of supply disruption will have a very negative effect on offensive operations, and if supplies are cut off altogether, any units of the German Army remaining in England will inevitably be destroyed.

          Honour.

          But do set up a social group for the German team so that you can have genuinely confidential discussions and issue confidential orders.

          I am stealing the forum logistics for this game (separate open threads, social groups) from The Purist's game which has been running for over a year, and which hasn't seen any problems due to people peeking at other teams' threads!

                            Right... remaining German briefings.

                            Luftwaffe briefing

                            Operational strength as of T-Tag consists of

                            Fighters
                            Me109 - 458
                            Me110 - 145

                            Bombers
                            Ju-88 - 83
                            He-111 - 287
                            Do-17 - 101
                            Ju-87 - 170

                            The relative performance of these types should be familiar to you - the only thing to note is that the Ju-87 is much the strongest anti-shipping unit while the other bombers and the Me-110s have some anti-ship capabilities.

                            Many squadrons are somewhat below their assigned levels as heavy losses have been sustained in the fighting over England so far. While both men an airframes are tired, morale is high, since the British are on the run.

                            The Luftwaffe is also responsible for the 7. Flieger Division, composed of 4 Parachute and 3 Glider regiments. While these troops will fall under Army command when they arrive in Britain, the LW has the final word on how they are deployed in support of the invasion. Do they drop close onto the beach-heads? Do you try to pull off an Eben-Emael style coup de main on a fortified British position like Dover? Should they be deployed inland to interfere with enemy communications?

                            Intelligence suggests enemy fighter strength on operational squadrons as about 250 monoplane fighters. Enemy bomber strength is about 300 including both light and heavy types. The only really dangerous British aircraft is the Spitfire, which is at least a match for the Me109, and Spitfires make up no more tha n1/3 of their fighter strength. However even the technically obsolescent Hurricane needs to be handle with respect. British bombers are also compare poorly with our modern types, though our dDo-17 and Ju-87 bombers have also proved vulnerable in recent months.

                            The RAF has been thrown out of the South East corner of England and we expect air superiority over our landing areas. However we are unlikely to have Air Supremacy for an extended period of time, in spite of Reichsmarshall Goering's opinions. Britain still has plenty of planes, pilots and production capacity.

                            Mission.

                            The Luftwaffe is responsible for
                            - maintaining air superiority over the Channel and the English battlefields
                            - supporting the Heer by providing close air support to our troops and interdicting enemy lines of communication
                            - supporting the Kriegsmarine and the invasion fleet by destroying Royal Navy warships in port or at sea

                            Even with superiority in numbers, quality of machines, and morale, this will require great skill.

                            Each air unit (assigned strength of anywhere between 15 and 50 planes) can be assigned one or more of the following tasks:

                            1) Attacking a specified hex: useful for to 'soften up' a given enemy position prior to, or during, an attack. Can also be given a mission to attack an airfield or bridge.
                            2) Air Superiority. The unit seeks to engage enemy air units undertaking missions anywhere on the map in this an the subsequent enemy turn.
                            3) Combat support. The unit seeks to engage in support of any friendly ground or naval unit making an attack, or in the subsequent enemy turn to defend any friendly ground or naval units under attack
                            4) Interdiction. The unit seeks to attack enemy units moving behind enemy lines, and also gives a small penalty to enemy supply.
                            5) Rest. The unit undertakes no combat mission and instead recovers its readiness and receives replacements (if required).

                            Units can potentially engage in several mission/engagements in a (one-day) turn. However the more they fly, the lower the unit's Supply and Readiness scores become. If Readiness is too low, or heavy casualties are received, then the unit spends one or more turns Reorganizing and is out of the equation temporarily.

                            The Reichsluftministerium needs to decide how best to fulfill its missions.

                            Should everything be devoted to covering the landings? Should any units be assigned to Interdiction duties to prevent a British counter-attack from forming up? Should Stukas be held in reserve against an intervention by the British fleet or be committed to support the beach-heads? How quickly should units move to captured airbases in occupied Britain? Do you want to keep up the pressure on the RAF by bombing its bases?

                              Kriegsmarine Briefing

                              The Kriegsmarine faces possibly the greatest challenge of al lthe German services. Without control of the seas the Army cannot conquer Britain, and control of the seas must be achieved with distinctly inferior resources.

                              The Kriegsmarine order of battle is:

                              2x Battleship - Scharnhorst, Gneisenau
                              2x Heavy Cruiser - Admiral Hipper, Blucher
                              4x Light Cruiser
                              16x Destroyer
                              Miscellaneous torpedo boats, armed minesweepers, etc represented by a total of 6 "Destroyer (Early)" units.

                              Against this, the British have at least 3 battleships in the North Sea and more in reserve, as well as at least 40 destroyers and 10 cruisers in the Channel area an more in reserve.

                              As noted in the Supply briefing, the health of the invasion depends on your ability to occupy coastal sea hexes which contain Supply Points and hold them against British counter-attack. There are many open questions...

                              1) Do you want to commit the Scharnhorst and Gneisenau to the Channel, or send them into the Atlantic? If they are unleashed in the Atlantic it is likely that the will tie up larger numbers of RN warships which could otherwise be deployed in the Channel. However this would mean that the two battleships were not available in support of the invasion. Bear in mind that the English Channel is a very risky environment for anyone's capital ship- a torpedo attack by a British destroyer could put either battleship out of action indefinitely...

                              2) How should the fleet be deployed to support the invasion? This is an open question. Currently the fleet is deployed with one Light Cruiser supporting each of the major fleet units and the destroyers formed into 4 squadrons of 4 ships, and the miscellaneous craft formed into 2 squadrons. However this is open to revision. OKM needs to give orders regarding the disposition of the ships - on the flanks of the invasion fleet? in the middle of the fleet? - and for ensuring that the Luftwaffe provides sufficient air support.
