The prelude to the classic Avengers/Defenders war took place in the September 1973 stories of each title, kicked off in separate epilogues following their main stories. In sequence, the first to read would have to be the epilogue of Avengers #115, which segued to its follow-up in Defenders #8--both of which can be sampled in a separate post. The two segments are driven by the common denominator of the Black Knight--his mysterious disappearance and his fate, respectively--but the main Avengers tale gets short-changed a bit, since what the team discovers at the site of Garrett Castle is a separate encounter that must play out before they move on to address the mystery of the Knight, and that story as a result is given limited space to pique the reader's interest.
On the other hand, the foe the Avengers face is not a powerful one nor a particularly formidable one, considering that the lineup of the Avengers at this point in time is unquestionably both--and so the story doesn't necessarily require a great deal of space to be resolved. (In fact, all things considered, it may be using too much space to dispatch the opposition.) But with other elements in the story taking up the Avengers' time, there are only eleven pages to dedicate to the main conflict--roughly the same amount of pages that stories in Tales Of Suspense, Tales To Astonish, or Strange Tales had available for splitting their issues between two heroes in separate stories.Yet, even wedged in as it is, "Below Us The Battle!" doesn't fall into the category of a throw-away story, and it certainly isn't filler material. Yes, the Avengers probably have more trouble with their foes than might be reasonable to expect for "Earth's mightiest heroes"--and yes, it's confusing to see the Avengers so at a loss to handle superior numbers, given how they met and vanquished a mass of armed warriors far more adept at savage combat and with far greater armament than the primitive foes they face here. But the circumstances of the encounter are intriguing enough to leave you at least satisfied, while the bookends of the Defenders plot are sufficiently distracting to supplement any perceived weaknesses in the main story.
There's also the added benefit that writer Steve Englehart is finding his legs with the Avengers, and so there's no shortage of continuing character development. In this case, the Swordsman, their newest member, finds that he's persona non grata in the U.K. when the Avengers quinjet, on its way to the Black Knight's ancestral castle, is boarded by a S.H.I.E.L.D. craft that's been dispatched to deliver a brief but blunt message for the team:
(Does this SHIELD agent think he's landing on the moon?)
