gondors armies vs. rohans

[Boromir88]

When Gandalf asked "Where are Gondor's armies?" I think he was questioning why they were not on the front. It seemed that Denethor had not sent nearly enough troops to hold Osgiliath. Most of them were probably kept in the city, where they were useless. So Gandalf was really saying "Why are your soldiers hiding in Minas Tirith when that's not where the battle is?"

I thought of it as totally different. The wonderful section in "Minas Tirith" we see all of Gondor's armies from the outer regions coming in for the defense of the city. I thought of Gandalf's saying as Denethor didn't send out word to come to Minas Tirith and make a stand, basically Gandalf saying "Denethor why didn't you send word for men to come in and fight..." Because right after this Gandalf says "Send word to Theoden of Rohan. You still have friends...etc"
