Try this switch
/m maxerrors Maximum number of errors that can occur before the BCP operation is terminated. Each failed insert counts as one error. Default value is 10 (optional). If a value larger than 65,535 is specified, this field is set to 65,535.
I would suggest for safety though also do an /e and output errors to a file for easy reference.
You may also need to break the batch down if you will have more than 65535 errors possible.
