As a lorry driver, you're legally required to check your load frequently, especially when crossing borders. There's no way you could miss that many people.
He's legally responsible for his load regardless of whether he was "in on it" or not, just like you are responsible for the contents of your suitcase at airport customs even if someone else packed it.
Err, he didn't take the trailer across any border, he only picked-up from the UK docks about half an hour before he seems to have checked the load & called 999.
