How many umbar corsairs were going to minas tirith?

I just want to know because in the film they look very weak for sauron to even want them there it looked like they had 200 men and why would the orcs that retreated care i cant recall seeing it in the book i read it 3 years ago so i cant remember thanks

Hey dude,

are you meaning the ships that Aragon and co defeated before they arrived? mmm.. trying to recall the EE version of ROTK but I do think there was alot of ships coming through the river. Way more than 200 men.
