I had much more trouble with this than what I'm comfortable admitting. But here are the locations. Right next to the windmill there is 2 crates and 1 barrel. At the front gate of the city, beneath the gigant red banners on both sides of the stairs there are a total of 4 crates 1 barrel and a bunch of urns. On the right side of Valy's lab entrance near the fence there's 1 barrel and some urns.
