Australian infantry attacking behind a creeping barrage, 18 September 1918. This rare photo of infantry in action shows how thin a creeping barrage could be. This barrage is probably doing more to show the Australians the right direction than it is to suppress German fire. The cloud in the left center is probably a recently-landed smoke round, while the smaller clouds are dust and the small puffs of smoke are ordinary rounds. The photo also shows another development: the infantry have enough fighting power to fight on their own, instead of relying on the creeping barrage to suppress most German resistance.
