Arty is a *****. Depending on your Core Forces the AI will adjust up/down and buy accordingly. Sounds like your deployment may have cost some as well. I am in a long 43-45 Campaign on my 7th battle. My core is about 4005 and I have been on the Eastern front for all 7. Right now my center Rifle Company is getting slammed by at least 3 batteries of 122mm. Nothing to do but try to get out of it or wait it out. I used in one of my advances I think 1 module of 170, 2 of 150 and 4 of 105's it crushed the Soviets and my core just mopped up.

Polish forces are dirt cheap and sounds like the AI decided to use lots of Arty for his assault. Also if you setup right in or near the VH the AI will pound those hexes so you need to defend accordingly.

Best of luck
