"A Good Man Goes to War" is the seventh episode of the sixth series of the British science fiction television series Doctor Who, and was first broadcast on BBC One on 4 June 2011 and served as a mid-series finale. The episode was written by Steven Moffat and directed by Peter Hoar.
The episode follows the cliffhanger of "The Almost People", which reveals Amy Pond (Karen Gillan) had been operating a Flesh duplicate of herself and is in fact held in a remote location and about to give birth. Alien time traveller the Doctor (Matt Smith) and Amy's husband Rory (Arthur Darvill) muster an army of allies and set out to find both Amy and her child, a girl named Melody Pond.
The episode reveals the recurring character River Song (Alex Kingston) is Amy and Rory's child. River's identity was kept in top secrecy, and only a few members of the cast and crew were issued the correct ending of the script. The beginning of the episode contained many different locations which were challenging for the production team. The main setting, Demons Run, was filmed in a military base and hangar in Cardiff. "A Good Man Goes to War" was watched by 7.57 million viewers in the United Kingdom and received an Appreciation Index of 88. Critical reception was mixed to positive, and the episode was nominated for the 2012 Hugo Award for Best Dramatic Presentation (Short Form).
On 28 May 2011, immediately following the broadcast of "The Almost People", the BBC released a prequel to "A Good Man Goes to War". The prequel had Dorium talking to two Headless Monks. He gives them the brain of a Judoon, which contains a security protocol the monks need. Dorium tells them he knows what they are up to, as he has heard rumours around the area. He asks them, "All this, to imprison one child? Oh, I know what you're up to, I hear everything in this place. I even hear rumours about whose child you've taken. Are you mad? You know the stories about the Doctor? The things that man has done? God help us if you make him angry!"
The Doctor (Matt Smith) and Rory (Arthur Darvill) have discovered Amy (Karen Gillan), Rory's wife and the Doctor's companion, has been abducted from them and her place taken by an avatar made from "the Flesh", a semi-sentient being which can create near perfect replicas of other individuals, and are able to change their molecular structure to suit their surroundings or needs ("The Almost People"), through which Amy has been experiencing events as if she were physically present. The Doctor has come to learn the real Amy is being held on a secret asteroid base called "Demon's Run", and collects several old debtors from across time and space to lay assault on the base, including Sontaran Commander Strax (Dan Starkey), Silurian Madame Vastra (Neve McIntosh) and her human wife Jenny Flint (Catrin Stewart), and the black market trader Dorium Maldovar (Simon Fisher-Becker). Rory, after collecting information on the base's location from a Cyberman fleet, attempts to recruit River Song (Alex Kingston) from her Stormcage prison cell, but she refuses, saying she cannot be with the Doctor at this time as this battle is when he will discover her identity. Aboard the base, Madame Kovarian (Frances Barber), who has been watching over Amy during her pregnancy and has taken her child, Melody, from her, prepares her human troops to fight the Doctor alongside the Order of the Headless Monks who reside at Demon's Run; the monks are literally headless and incapable of being fooled or intimidated. Human soldier Lorna Bucket (Christina Chong), who met the Doctor as a young girl in the Gamma forests, attempts to befriend Amy, giving her a good luck token made of cloth sewn with Melody's name on it in the language of the Gamma forests. Amy warns Bucket of the Doctor's fury if she fights against him.
Assisted by additional Silurian and Judoon forces, the Doctor and his allies launch a surprise attack and secure the base. The Doctor and Rory free Amy and retake Melody before Madame Kovarian can escape with her. As the Doctor celebrates, considering this his greatest achievement, Vastra and Dorium discover Kovarian has been scanning Melody and has found the child has both human and Time Lord DNA. The Doctor surmises Melody was likely conceived on Amy and Rory's wedding night aboard the TARDIS ("The Big Bang"), the baby's DNA influenced by the time vortex. The rest of the Doctor's allies regroup, and Amy and Rory tend to their daughter using an ancient wooden baby cot the Doctor claims was his own. Meanwhile, Bucket has arrived and warns the group of Kovarian's trap, but they are too late, as the TARDIS is blocked by a forcefield. They are attacked by the Headless Monks, and several Silurians are killed immediately. Dorium is beheaded, while Strax and Bucket are fatally wounded in the battle. Meanwhile, Kovarian, well away from the base, contacts the Doctor, explaining they will be using Melody as a weapon in the war against him. She takes delight in telling him he has fallen into another trap, and "fooling [the Doctor] once was a joy, twice in the same way is a privilege". The Doctor races to the hangar to warn his friends, unaware he is too late. At the same time, Kovarian appears to Melody in a hatch in midair, as she had to Amy's Flesh duplicate, and tells the baby to wake up. The baby dissolves into the Flesh liquid, leaving Amy horrified and in shock.
The Doctor arrives too late to help his wounded allies, and so he and Rory console Amy. Lorna Bucket dies, remembering her childhood adventure with the Doctor. River appears, and the Doctor berates her for not helping. She tries to explain she could not have interfered in these events, and tells the Doctor what transpired was partially his fault, having been brought about by those who feared his reputation. The Doctor becomes angry and demands to know who she is. River shows the Doctor the cot, and The Doctor recognises River's identity. Elated, he goes off on his own in the TARDIS to rescue Melody, asking River to return everyone to their proper time period. Amy, holding a gun at her, demands River explain what she said to the Doctor, and so River shows Amy and Rory the cot. Initially Amy believes River is referring to the Gallifreyan symbols engraved on it, but they cannot be read by humans even with the aid of the TARDIS translation system. Instead, River shows them Bucket's cloth prayer leaf with Melody's name, still in the cot. Amy tells River she knows her daughter's name; River tells her the people of the Gamma Forest do not have a word for "Pond", as the only water in the forest is the river. As Amy and Rory stare at the prayer leaf, the writing is translated into English, revealing the child's name: River Song.
The Cybermen that appear in the episode are intended to be from Mondas, rather than the parallel Earth seen in "Rise of the Cybermen"/"The Age of Steel". Rory wears the armour of a Roman centurion, as first seen in "The Pandorica Opens"/"The Big Bang." The Fat One and Thin One refer to the Doctor sending the Atraxi away from a planet before calling them back "for a scolding," an incident which took place in "The Eleventh Hour." "The only water in the forest is the river," the phrase River uses to explain why the people of the Gamma Forest translate "Pond" to "River," was first said to Rory by Idris in "The Doctor's Wife." In the seventh series opener "Asylum of the Daleks" it is revealed that Amy's experiences on Demon's Run rendered her infertile.
"A Good Man Goes to War" is the seventh episode of series six and also the 777th episode of Doctor Who, but there are no seven puns as the production team did not realise this until after shooting. The episode's idea stemmed from lead writer and executive producer Steven Moffat wondering if the Doctor, who was typically a pacifist, could be provoked enough to assemble an army. The Headless Monks were first mentioned in "The Time of Angels", added to that episode's script to help explain the monastic look of the Delirium Archive the Doctor and Amy were visiting. Similar troops also known as "Clerics" appeared in "The Time of Angels"/"Flesh and Stone"; Moffat stated it seemed many armies in the future in Doctor Who were of religious origin. The possibility of the English word "doctor" originating from the Doctor was a notion made by Moffat on Usenet in 1995.
Moffat had planned the revelation about River Song "for a long time"; when creating Amy, he chose "Pond" for her last name to create a link. Moffat intended for the "answer to be as complicated as the question". Moffat informed Kingston of the secrets of her character at the end of the previous series and she was not allowed to tell anyone; Smith, Gillan, and Darvill were unaware of the identity of her character. River's identity was kept in top secrecy; the script read at the read-through had a false ending, and only a select few were issued the real script.
The episode sees the return of several minor characters. Dorium previously appeared in "The Pandorica Opens", while Henry and Toby Avery from "The Curse of the Black Spot" and the Spitfire pilot Danny Boy from "Victory of the Daleks" make cameos. Moffat said he planned writing in a cameo for John Barrowman to reprise his role as Jack Harkness, but Barrowman was busy filming Torchwood: Miracle Day and was unavailable. Originally the episode contained a scene with Ood Sigma, previously seen in "Planet of the Ood", "The Waters of Mars", and The End of Time, but it was cut from the final episode. Russell T Davies is still listed in the credits for creating the Ood.
"A Good Man Goes to War" began shooting in mid-January 2011. The various sets seen at the beginning of the episode were challenging for the production team. A Cardiff alleyway was dressed to look like a Victorian street for a brief introduction scene with Vastra, while a hotel bar in Cardiff was used for Dorium's nightclub. Demon's Run was filmed in a military base and hangar in Cardiff. Steam was added to the set to give it a more spaceship-like feel. The army of clerics was made larger with visual effects. The set used for the chamber Amy was kept in was the same used as the Oval Office in "The Impossible Astronaut"/"Day of the Moon". Baby Melody Pond was played by twins, a common practice used in filming so that one twin can rest while the other is on set. The twins were three months old. Gillan and Darvill were both nervous about holding the infants, but they felt it added to their acting. Gillan stated the episode showed a different side of Amy and thought female viewers would sympathize with her.
The Headless Monks were played by stuntmen, and so the actors were free to improvise on their choreography when fighting them. For the scene in which the hoods of the Headless Monks are pulled back, a shoulderpiece was created for actors who were shorter than the ones who normally portrayed the monks. Dan Starkey, who plays the Sontaran Commander Strax, previously appeared as Sontarans in "The Sontaran Stratagem" / "The Poison Sky" (2008) and The End of Time (2010). Neve McIntosh, who played the Silurian Warrior Vastra, previously played the sisters Alaya and Restac in "The Hungry Earth" / "Cold Blood" (2010). Both Starkey and McIntosh underwent extensive make-up and prosthetics for their characters.
"A Good Man Goes to War" was first broadcast in the United Kingdom on 4 June 2011 on BBC One and BBC HD and in the United States on BBC America on 11 June 2011. UK overnight figures showed the episode was watched by 5.5 million viewers, a rise of a half a million from the previous week and coming in sixth place for the night. Final consolidated ratings showed the episode was watched by 7.57 million viewers with an audience share of 31%. It achieved an Appreciation Index of 88, the joint highest for the series at time of broadcast.
"A Good Man Goes to War" has received mixed to positive reviews. IGN's Matt Risley rated the episode 9 out of 10, describing it as an "epic" mid-series finale which "opened with a grandstanding, wonderfully OTT pre-credits tease and didn't really let up from there". He praised the spectacle and character development, but felt it led to a certain amount of "the odd rushed scene...forgettable supporting [characters], and little opportunity to develop the Headless Monks into anything particularly imposing". Dave Golder of SFX gave "A Good Man Goes to War" four and a half out of five stars, feeling it "saved" the sixth series and offered "a satisfying slice of fantasy television which ticked lots of boxes: it featured dashing, daring storytelling which was bold and confident; it looked fantastic, there were some hilarious lines and the performance of the star upped his wattage a couple of notches once again". However, he was more critical of the Headless Monks and the direction of the battle at the end. Neela Debnath of The Independent was also favourable, praising the use of the cliffhanger and felt the complicated nature of the episode "draws people more into the show and gets them thinking about it".
Gavin Fuller of The Daily Telegraph said the episode was good but lacked significant background motivation into the villains. Fuller also noted the revelation of River Song being Amy's grown up child "is perhaps a narrative strand which would sit uncomfortably with a series where loss has often been brushed off as soon as the next couple of episodes". However, he did have praise for the performance of Smith's Doctor, commenting "the last few weeks have seen Matt Smith's Doctor in a welcome generally more serious vein, which he kept up here, with leavening at the right moments where his alien lack of comfort with human emotions, although used to comic effect, rang very true, as did his awkwardness when discovering the truth about River".
Dan Martin of The Guardian was less favourable, stating the producers "promised us a cliffhanger, and now we're left the whole summer long to contemplate whether our favourite show can really have just dropped the ball. Oh there was plenty to love about this mid-season finale, and even more to pick over. But as an hour of drama it was all over the place". Because the episode was so fast-paced with little being explained, he did not feel any emotional connection to the Anglican marines or Lorna Bucket. Unlike Fuller, Martin was not favourable to Smith's Doctor, stating "the non-event of the battle means the Doctor never really gets to show this dark side we've been hearing so much about" and that Smith's predecessor, David Tennant, "got angrier most weeks". Martin did have praise for the final reveal of the episode, stating that although it had been "hidden in plain view from the very beginning as soon as it's revealed Amy has called the baby Melody", he was unable to make the connection and was suitably surprised. Martin later rated it the second-to-worst episode of the series, though the finale was not included in the list.
The episode was nominated for the 2012 Hugo Award for Best Dramatic Presentation (Short Form), though it lost to Neil Gaiman's episode "The Doctor's Wife".
Two of the new characters introduced in the episode, a 19th-century crimefighter Silurian named Madame Vastra and her assistant Jenny have proven quite popular among fans, with numerous forums and SFX calling for the BBC to commission a spin-off series. Steven Moffat stated in an interview that he did not have time to work on a spin-off but was open to the possibility of the characters returning. Vastra and Jenny, as well as a revived Strax, were made a recurring part of the seventh series.
