Naruto Thread (Spoilers For Sure)

There were no clones, they dismissed the jutsu right after the red sun barrier was blown up. The scary thing here is the fact that both full powered Hashirama and Tobirama were trashed in a single blow, which by the looks of it wasn't even a serious one. And I'm pretty sure Hashirama is basing his judgement on the fact that Obito broke the myojinmon and the red sun barrier like they were made of paper.

Hashirama that got torn in half was a wood clone. The ones in front of Madara were shadow clones.

The real Hashirama is still in sage mode, not to mention the fact that it's easy to tell the difference between Tobirama's half (small pieces of paper) and Hashirama's half (wood rings).
