Genuine question: why not simply pull its back in the reverse direction it was going, until its front is unstuck?

[sliken]

Because the momentum of a huge ship dug quite deeply into the sides of the canal quite hard, so it's no longer floating.

It's nowhere close to floating currently, and a ship can't be pulled with arbitrarily large forces without damage.
