τῷ ὅλῳ 5., 4., 49

[Constantinus Philo]

ἂν μὴ τῷ ὅλῳ ὑπολάβωσι τοῦ παντὸς κρείττους εἶναι:
I understand it as 'overall,' 'completely' but the translation renders it weirdly as 'that the whole of their force.'

[Hylander]

"Overall," "completely" would make τοῦ παντός redundant. The translation is right. Instrumental or comitative dative.

[Constantinus Philo]

The commentary says that τοῦ παντός refers to the other army.
