Australians set up dug-in in a pair of hexes two hexes north of 1821 with their mortar unit a further two hexes south. Italian mortar and offboard artillery traded fire with Australian mortar unit. Italian infantry advanced slowly southward and moved east, staying at 3+ hexes distant from Australian guns. Italians then moved west and entered hex 1821 after withstanding numerous opportunity fire chances. Australians should have set up one hex farther south, with 1821 adjacent to them. Need to play this one again.
