I've searched the phrase "Not a bad little haul" and got lots of hits. It seems a quite common phrase, but none of them addressed what it means. What does it mean truly?

Answer 1

A haul is the amount caught, fishing in a net, or more generally, the amount taken in another operation, such as salvage, or theft.

not a bad (little) is an example of litotes, and means a good amount.

So a praphrase would be something like We've captured quite a good number of truants, maybe better than the average for one night.
