It's a reference to 468, silver.
So then what is the non-migrationist response? I understand that the WRE allowed different barbarian tribes to settle in the Empire, but was the WRE so impotent after the Rhine Invaders that they were unable to stop the Vandals from taking North Africa? I read a book by Peter Heather (can't remember the title) where he asserted that after North Africa was lost, the situation just became a downward spiral for the WRE and they were basicaly screwed after the ERE was unable to retake Carthage.
The non-migrationist response would be that most of those "barbarian" kingdoms weren't really all that "barbarian" anyway, that most of the "barbarian" military forces were probably comprised largely of Romans, and that it's deeply unclear as to how much autonomy most of the "barbarian" tribes even had before the last decade or so of the WRE.
Heather is probably the most famous exponent of a kind of modified migrationism, revamped to get rid of the stink of Nazism and German nationalism and outdated 1920s concepts of migrations, peoples, and so forth. His explanations are decent, but his main thesis - that the arrival of the Huns caused a "domino collapse" in the peoples surrounding Roman territory, who started streaming into Roman territory, creating a security threat that destroyed the Empire - is somewhat flawed. For good explanations of the last century of the WRE that aren't migrationist, look at Guy Halsall,
Barbarian Migrations and the Roman West, 376-568 and Walter Goffart,
Barbarian Tides.
The loss of North Africa specifically had to do less with the crisis stemming from the Rhine invasion of the first decade of the fifth century - which had mostly been solved by 420 or so, as even Heather will tell you - and more with the civil war that erupted over control of the imperium in Rome after the death of Constantius III (423), which got worse with the death of Honorius (425). Until the 430s, the Roman central authorities could do little to deal with the Vandals in North Africa. Subsequent efforts to take North Africa back (in 439-40, 457, and 468) ended in defeat, each due to contingent events - one was aborted because of the security threat of Attila, one because of a successful surprise attack, and one because the wind changed.
I personally would not say that the WRE was 'doomed' until it stopped fighting. One might locate that in 471, when the offensive of the Emperor's son, Anthemiolus, against the Visigoths in southern Gaul was defeated. Evareiks, the Visigothic leader, also successfully defeated the army of a Roman ally, the mysterious Briton Riothamus. Another might locate it in 475, when Iulius Nepos' planned offensive into southern Gaul was aborted by the revolt of Orestes and Nepos' dethronement in favor of the (in)famous Romulus Augustulus. And one might even argue against the very concept of the fall narrative, objecting that a division into Western and Eastern Roman Empires is a modern artifact which has no place in a discussion of late antique Roman politics, and a fundamentally silly thing to talk about.

It is my understanding that the Prussians were better trained and had better weapony.
That is only partially true, and only helps in describing why the Prussians won, not why the war ended so quickly.
