And Sauron's bombs were used to blast multiple large holes in the Pelennor Wall.

An explosive device was indeed used to break through the Rammas Echor. Sauron possibly gleaned the information from Saruman's mind while he used the palantir? Or: "Walls stand up no longer: gorgûn knock them down with earth-thunder (?) and clubs of black iron."
