2 Introduction There are ten scenarios. The first five are presented chronologically to study the tactical action at the dams, incorporating only the rules of Part 1 [rule sections 1.0-5.0]. Except for Scenario 1 they are brief affairs, good for learning the game but mainly intended to present each fragment of the raid as it was about to happen. Each includes a unique Debriefing Chart. For a more prolonged experience, attack scenarios may be combined, thus capturing the entirety of the raid while providing more game [p.18]. If you are new to Enemy Coast Ahead, Scenario 5 is a good place to start [p.15]. Scenarios 6-8 add the rules of Part 2 to those already learned, and make full use of the Flight Map. They explore the fate of the three forces launched on the night of May 16, 1943. Scenario 9 treats the flights and attacks of all three forces as a whole, the complete historical scenario depicting 617 Squadron’s first mission, the famous Dambuster Raid in its entirety. A variant of Scenario 9 allows you to deviate from the squadron’s historical organization. Scenario 10 is the complete game, the “Campaign Game,” incorporating Part 3 of the rules. It abstractly treats the planning that led to the raid, and allows control over the organization and training of 617 Squadron and the assignment of targets. setting up Set up instructions are provided for each scenario, including a brief historical narrative. outcomes[5.3] Each scenario has a Debriefing Chart with “outcomes”. Generally, the higher up the chart your outcome, the more successful your mission. Historical outcomes are boxed. Locate your outcome by reading the Debriefing Chart left to right, column by column. Each column poses a question that will lead you to the next column until you find your specific outcome.

For example, in Scenario 1 [p.5] you first must answer the question of the dam’s status, breached or not breached (first column). Then, you must tally the number of Lancasters that survived the scenario, and then tally the number of ordnance still carried by your Lancasters (2nd & 3rd columns). Thus, if you breached the dam, had 4 Lancasters returned to base or still flying to Eder Dam, and still had 3 Upkeep in play, your outcome would be “worth the price?” attack scenarios (scenarios 1-5) aircrew training levels [4 2.2, 4.2.3, 4.2.13] Record the training levels of your aircrews on the Train- ing Level Track located on the Mission Planning Blotter approach and release chits [2.6] on the extreme left of the mapsheet.

12 Scenario 4: Second Attack on the Sorpe Dam Sorpesee Reservoir, 0314 hours, May 17, 1943

Flight Sergeant Brown at the command of AJ-F received Ultimately, AJ-F made six runs at the dam. On the last orders to attack the Sorpe Dam via wireless telegraphy one Upkeep was released and it rolled into the water, while in the air. Had AJ-T transmitted Goner78C exploding as desired. In fact, after climbing and circling, promptly two hours earlier, Grantham may have ordered a Brown observed the geyser of debris and spray leap out different primary target for AJ-F.

Maintain- ing low altitude was a challenge. Upon arriving at the reservoir, Brown descended in between the hills on either side and made an initial pass. He found it difficult to judge the approach in the darkness, and admitted that he botched the first pass. He circled round, made another pass to judge the trajectory, then instructed flares be dropped at several points along and around the path of flight as navigational aids.

15 Scenario 5: Attack on the Ennepe Dam? Somewhere in the Ruhr, 0330 hours, May 17, 1943

While already in the air, Flight Sergeant Townsend piloting the mine would come to light suggesting that AJ-O AJ-O received orders via wireless telegraphy to attack attacked the Bever Dam.

The wave took off at 2100 hours, the first of 617 Upkeep distorted compass readings, and the practice at Squadron’s bombers to rise into the night towards the Scampton had been that after installing the mine aboard dams. The flight route passed over the Dutch Frisian Island the Lancaster, the compass would be calibrated. The chain, a longer route necessitating their early take-off. readings were then recorded on a card, allowing the AJ-E flew over Vlieland first, at 2255 hours, and must have navigator to compensate for the presence of the mine alerted flak gunners below because they opened fire on the during flight. AJ-T had just arrived at Scampton, and its next Lancasters. AJ-W was hit by 20mm anti-aircraft fire mine had been installed but the compass had not yet that knocked out its VHF radio, rear gun and compass, been calibrated. This meant that McCarthy’s navigator inspiring Flight Lieutenant Munro to turn the Lancaster could not rely on the compass until Upkeep was back to Scampton. Meanwhile, AJ-K had drifted a few released. kilometers south and climbed to nearly 500 feet before visually confirming bearings, when it too was hit by flak. Unable to catch up with the formation he was supposed The Lancaster was set ablaze and crashed. Next in line, to lead, McCarthy piloted AJ-T towards Sorpe as best he Pilot Officer Rice kept AJ-H so low throughout the cross- could. The Lancaster encountered a variety of challenges sea route that by landfall the bomber had to veer in order along the way. The crew spotted nightfighters overhead to avoid sand dunes.

After several the Rhine. runs Sgt. Johnson released ordnance and McCarthy headed home. All this action alerted the local nightfighter wing, and several Me110s from Leeuwaarden were scrambled, but cruising at over 3000 feet their pilots were unable to spot the only Lancaster of the diversionary force still flying, the late-comer AJ-T. Flight Lieutenant McCarthy was a veteran pilot, an American who had joined the RCAF in 1941, and now commanded a less experienced aircrew. He was supposed to take off with the rest of the diversionary wave, but one of his Merlin engines leaked coolant, so he and his crew abandoned AJ-Q and hastily boarded AJ-T.

29 Scenario 9: The Dambuster Raid This scenario combines Scenarios 6-8. Your goal is to breach two dams, or more, and you have 19 Lancasters to work with. The Alert Level begins at 1, and the Recon Levels of all dams is 1, except Möhne, Eder and Sorpe which are at Recon Level 2. All hostile Flight Zones are at Recon Level 2 as well. All Activity Levels are 0 (zero) and all Water Levels are Full. Flak at Möhne is at Level 3 but all other defense levels (at every dam) are at Level 0 (zero).

31 outcome Scenario 9 Adolf Hitler is dumbfounded when his Minister for Armaments and Munitions explains the implications of the raid. a Through a shroud of rage he orders every measure necessary to repair the dams, defend them, and then demands to see a map highlighting every dam and reservoir in Britain. “Retaliation one-hundredfold” will be theme of his next radio address to the volk. Meanwhile at Scampton, returning flyers celebrate, and mourn those they left behind. A Victoria Cross is awarded, as well as a bevy of other decorations. Headlines in the British press offer hyperbolic accolades. The Daily Mail blares “RAF SMASHES GERMAN INDUSTRY,” while the Illustrated London News declares the raid a “TRIUMPH.” Air Chief Marshal Harris later personally congratulates Barnes Wallis, offering support for any other ideas the engineer might have. In years to come historians will include the Dambuster Raid on the list of the war’s strategic turning points. b When Air Chief Marshal Harris hears that none of the Lancasters in 617 Squadron returned to Scampton, he is dumbfounded. From the very beginning he was suspicious of the bouncing bomb’s efficacy, and while waiting to hear details he begins a letter intended to remove Barnes Wallis from all association with the RAF and the Ministry of Aircraft Produc- tion. But then he receives the full report of breached dams, confirmed in the morning by reconnaissance aircraft, and his zeal dulls. The engineer’s unlikely device not only worked, it proved to be of strategic importance. Without apparent irony he is heard to exclaim, “I’ll be damned.”

c After several days of inspections, Albert Speer, Minister for Ai cr w te Armaments and Munitions, reports that the RAF attempted to “strike at our whole armament industry by destroying the applies to outcomes on this page hydroelectric plants of the Ruhr.” In 48 hours Hitler approves To determine the fate of the crews lost over enemy territory, Speer’s ambitious plan to strip other factories to restore roll two dice: electrical power service and to repair the broken dams before the autumn rains commence.

Coastal Command relays this to 617 Squadron: “Well done Scampton. A magnificent night’s work.” Since so few Lancasters f were lost in the raid against the dams, the Germans remain oblivious of Upkeep. As one engineer confessed in his report later that month, “it is not known yet what type of explosive was employed.” Meanwhile, back in Britain, a Victoria Cross is awarded, as well as several DFC’s, DSO’s, CGM’s and bars, keeping the King busy at Buckingham Palace in June and July. With most of its aircraft and crewmen intact, 617 Squadron is assigned other challenging and vital targets, including the German battleship Tirpitz using another device engineered by Barnes Wallis -- a ten-ton bomb codenamed Tallboy.

32 outcome Scenario 9 Air Vice-Marshal Cochrane signals this from Grantham: “All ranks in 5 Group join me in congratulating you and all in 617 g Squadron on a brilliantly conducted operation.” Air Chief Marshal Harris personally attends several of the debriefings, along with Barnes Wallis, where Harris congratulates the engineer and tells him that his skepticism of the bouncing bomb is no more. Shaking his hand he exclaims, “you can sell me a pink elephant.” In the Ruhr Valley, several powerstations are no longer operational, knocked out by floodwaters. The Möhne in particular gushes a tidal wave damaging roads, buildings, sweeping away bridges and inundating buildings as the water rises more than thirty feet. A 20-ton turbine is washed away and the dam’s torpedo netting is forced through the breach. The water let loose by the Eder rises more slowly as it fills the broader valley, but ultimately it rises higher, just topping 39 feet. Civilians scramble out of the way as best they can, but more than a thousand of them die. The raid is a success, but a problem comes to light. Despite the safety precaution of Ai crew ate h a self-destruct detonator fixed to Upkeep, the RAF soon learns that the Germans applies to outcomes on this page managed to get their hands on an intact mine.

The losses are so great that the squadron is decommissioned, its Germans learn the technical remnants transferred to other units. Barnes Wallis is also disturbed by the losses, so details of Upkeep; much so that he considers shelving schemes he has for other ordnance. The casualties suffered by 617 Squadron that night have long-lasting impact. 7-9 several flyers parachute Decades after the war, one surviving pilot will tell a British reporter that, “To this safely or survive crashes, and many are badly injured; day, I think about the ghastliness of the numbers.” Over the years British tourists captured within days, some will visit the site of the dams, as well as the many places where 617 Squadron’s die before their transfer to Lancasters hit the ground.

If ODD, the casualties suffered by 617 Squadron are deemed too great by Air Marshal Harris. He is not even convinced the mission was a success. There will be no follow-up raid. Air Vice-Marshal Cochrane signaled this from Grantham: “All ranks in 5 Group join me in congratulating you and all in 617 m Squadron on a brilliantly conducted operation.” Privately, he is disturbed by the losses suffered by the squadron, and his boss, Air Chief Marshal Harris, states flatly that the mission can scarcely be considered a success. Harris is determined that another Pyrrhic disaster like this one will not be perpetrated on his flyers, and he writes a letter to the Air Ministry requesting that Barnes Wallis no longer receive support for his “experiments.” Meanwhile, the Air Ministry is feeling pressure from a Parlia- ment minister who is convinced that British and Scottish dams are vulnerable to the same kind of bouncing bomb attack. Intelligence soon learns that at least one Upkeep has been recovered intact by the Germans, lending urgency to fears of retaliation. By the end of June, anti-aircraft guns, searchlight batteries and smoke cannons are installed to defend nearly a dozen dams. © 2014 GMT Games, LLC

scenario 10 Debriefing happens as a five-step process. Each of the first three steps has its own Debriefing Chart and outcomes, and will award you VP. In Step 4 total the VP awarded in Steps 1-3 to determine the political outcome. In Step 5, determine if there will be a follow-up raid. Instructions for the follow-up raid follows Step 5. step 1 debrie ng: 5 Group Was 5 Group affected adversely by the raid? To evaluate the impact of 617 Squadron’s casualties on 5 Group, add the requisition points of all destroyed aircrew (that is, of all aircrew that did not return to base at the end of the game). Include aircrew destroyed during training (crashed). Then, add the number of Elite Crewmen markers attached to Lancasters that did not return to base. The sum is the “crew loss”. The immediate effect on 5 Group is indicated in the chart. Also, note the victory points awarded to you. If the result reads “no follow-up raid,” then regardless of the Step 5 outcome, no follow-up raid is permitted (not by 5 Group anyway).

catastrophic (no follow-up raid) 617 Squadron was manned by the best aircrews in 5 Group, and a single raid has decimated its ranks. The squadron will be decommissioned and 5 Group will require personnel 36 or more transferred from other groups in Bomber Command to -3 maintain its effectiveness. Henceforth, the number “617” will be bad luck to superstitious airmen.

step 2 debrie ng: Bomber Command To determine Bomber Command’s evaluation of the raid, add the rv (reservoir value) of each breached dam [3.5.1]. Then, subtract the number of Lancasters that did not return to Scampton. Do NOT include those that crashed during training. Use the difference to determine the Bomber Command outcome, and the VP scored.

strategic turning point The raid demonstrated the vulnerability of Germany’s industrial capacity. Dams were breached, 18 or more thousands of civilians killed, agricultural land ruined, electrical power-stations obliterated, and bridges and roads washed away or crippled. A stunning victory!

decisive victory The success exceeded Bomber Command’s expectations, and the Prime Minister is certainly 13-17 pleased. The raid helps persuade the Americans that night bombing is a viable strategy against German war industries, and the Soviets are assuaged by the results.

major victory The raid was a success in every measure. Barnes Wallis is vindicated, and encouraged to develop other weapons. Bomber Command is given a mandate to aggressively pursue the engineer’s ideas, 11-12 and develop the tactics to deliver such ordnance where it can do the most harm.

The Germans were surprised, none more than Adolf Hitler who is marginal victory furious at the Luftwaffe for allowing such a transgression in the Ruhr. He orders the diversion of resources to protect the dams, siphoning 9-10 assets and personnel from other theatres. But his Armaments Minister, Albert Speer, emphasizes to the Fuhrer that the damage could have been far worse. encouraging but awed result The raid was successful, but not everything went as well as it should. Damage was inflicted on 6-8 Germany’s war industry, but was it enough? And did it warrant the investment in time, resources, and engineering that went into Operation Chastise? And now the surprise is gone.

inconclusive 4-5 The Prime Minister is not pleased. Too many resources were diverted for this project to net such a meager result.

The five games here offer cooperative or competitive play. Unless noted otherwise, all rules remain in effect.

Players must agree upon an organization and ers for their opponent. distribution of attachments, organizing the squadron into waves (6 total), assigning targets to aircraft. Example: Let’s say the Alert Level is 2. Player A has a wave in the Weser Flight Zone and Player B has two independent aircraft in that zone as This is a cooperative game, so although players maintain well. Player A will draw and assign Hazard markers on Player B’s control of their Lancasters they work together to achieve Lancasters, and then Player B will draw and place markers on Player A’s a positive result. Share approach and release chits, or wave. So, Player A adds up the number of Hazard markers he’s supposed divide into two sets (if you divide them, see p. 46). At the to draw: two independent aircraft plus 2 for the Alert Level, plus 2 for the conclusion of the game they share a single outcome, zone; he draws 6 Hazard markers and assigns 3 to each of Player B’s determined by using the Debriefing Chart in the Lancasters. Then, Player B returns the favor, but draws only 5 Hazard Scenario Book [p.30]. markers (2 for the Weser zone, 2 for the Alert Level, and 1 for the wave), placing them all on Player A’s wave. Evading and Resolving Hazards: Each player benefits from the Recon Level (i.e., each may Game 4 evade two hazards). Players assume control over the cooperative Hazard markers assigned to their waves and independent three-player aircraft during the Evade Hazards and Resolve Hazards Same as Game 3 except use only 18 Lancasters and Phases. Each player decides which Hazards may be evaded, divide them equally amongst the three players. and will assign Hazard markers to Lancasters within a wave.

That book was titled (e.g., Flight Commander A should get AJ-A, AJ-C, AJ-E, “Enemy Coast Ahead.” In game terms, Gibson was the “victor.” etc., and Flight Commander B should get AJ-B, AJ-D, AJ-F, etc.).

During the Wireless Phase, however, Second- ary Targets may not be assigned by any player. Who Gets Credit for Breaching a Dam? It is possible that Lancasters belonging to both players For example, Player A may assign Sorpe Dam as a wave’s Secondary may damage the same dam, but if such a dam is breached, Target, and Player B may do the same. only one player earns credit for the breach.

For example, AJ-A has precedence over If there are no winning players, all three lose. AJ-B. Flight Commander B is allowed a one-time override -- he may “go first” once, regardless of alphabetical order.

46 Dividing the Approach and Release Chits Several multiplayer games necessitate dividing the chits into two sets. When divided, each player uses only their own Set. Also, you may place the Dummy Run/Approach Observed marker only on Green aircrew. If you have two copies of Enemy Coast Ahead each player may use a complete set of chits (that is, 14 chits instead of 7), and the restriction on the Dummy Run/Approach Observed marker is lifted.
