This is an exact picture from a book i had as a kid, can't actually believe i found it, in that book it was iirc stated that some legionaires hacked the pikes, creating holes in the pike wall, then going in, and from then went forward. On the right side of the pic it's actually depicted, one or two Romans behind the Greek first line.
He he he, you actually found it eh? (i wish we could've found Samantha, doh! inside joke btw you and i )
That's interesting ! I guess that's one of the reasons why the Romans were so successful, its just that they were able to adapt to any military exigency (save for the Germanic issue, lol). They fought and conquered the Etruscans, the Cisalpine Gaul tribes, the Britons, were able to adapt and exterminate the Carthaginians, the Greeks (Sparta, Seleucid, Athens, Macedon), the Egyptians, the Judeans, the Dacians, the Thracians, the Dalmatians, Germania Inferior, Hispanola, and to an extent even sacked Cestiphon (the great city of the Parthian Empire), Armenia et cetera !
