At this time the Battery was raised as a part of the general expansion of divisional artillery prior to the AIF being dispatched to France.

In mid-March 1916 the battery sailed for France, and upon their arrival were issued with new 4.5 inch howitzers, reunited with their horses and commenced training.

Over the next two years, the 104th Field Battery, as part of the 2nd Division Artillery, saw intense and unrelenting action on the Western Front, with almost 58% of the total gunners deployed from Australia being killed.

On returning to Australia, the battery regrouped in Holsworthy, and moved up to Townsville in preparation for its second tour of Vietnam.

In February 1978, following a bomb blast at the Hilton Hotel in Sydney, the decision was made to call in the Army to secure Bowral, the venue for the Commonwealth Heads of Government Regional Meeting.

In October 1985 the battery was re-raised as an Army Reserve Unit, as part of 1st Field Regiment in Brisbane, and again issued with the 105mm M2A2 Howitzer.
