Wolf 359: The Massacre (part 1)

I have always had 1 question.

In voyager we see the Borg have thousands of ships of varying sizes and control a vast area of space. Voyager is able to take down spheres and small cubes.

Yet in Wolf 359 a single cube attacks and destroys hundreds of star fleet vessels. If a single cube is able to have that level of effect why didn't the borg commit a larger fleet?

You have the same issue in First Contact, they only commit 1 cube.

Considering how difficult the federation finds holding them back, attacking with 3-6 cubes would seemto assure victory

They would have to call cubes back from where they are pushing territory on the other side of their territory.

The Borg were not just fighting one species when they came to get the Federation, they were expanding outwards on all sides. So they committed the lowest level of resources they believed were necessary, and because the Queen was an arrogant fool, that was just one cube.

For First Contact, you can argue that having been thus far unable to assimilate the Federation they are unaware of the speed of human advancement. In the Star Trek Universe it has been implied that humans are EXCEPTIONALLY inventive especially when faced with a problem, and that the Federation is even FASTER than humanity alone because of the additional viewpoints added to human inventiveness. Basically, the Human Problem of Fantasy Games where the humans are an average, all-around boring species while Elves and Dwarves and others all have specialties? That's not applicable to Star Trek Universe, where humans are especially well-suited to be engineers, and highly valued for their social abilities which foster teamwork. The presence of humans in the Federation is one of the ingredients that makes the Federation uniquely effective at technological advancement. Not only is the Federation large and powerful, it advances more quickly than the species that the Borg have assimilated, and has advanced to a level that the Borg never allow other species to advance to, AND it advances the way the Borg do by peacefully trading and adding technologies when it admits new member species.

The Queen never dealt with a society like the Federation before, and she didn't expect them to advance very far beyond their capabilities at Wolf 359. She figured her cube was better, and that should be good enough and if by some weirdness it wasn't she would destroy the Federation by going back in time and destroying its weirdest, least predictable species: humanity.
