 For the eighteen months after its opening , the fort was manned by B company of the South Australian Volunteer Artillery but only on weekends . This changed in mid @-@ 1882 when South Australia 's first permanent military force was formed . The fort became the headquarters for the South Australian Permanent Military Force , then the state 's entire standing army of one officer and eighteen other ranks . Some of the unit was stationed at nearby Fort Largs from 1886 ; and , by 1889 the unit had grown to one officer and 45 other ranks . This force grew to 53 of all ranks by 1892 and was by then known as the Permanent Artillery . The unit trained 27 more non @-@ commissioned officers and men who were sent to man the King George Sound batteries near Albany , Western Australia . Though some of the gunners served in the Second Boer War , the unit itself never saw action . Fort Glanville 's section was called out in 1890 , marching to assist the police with a <unk> worker 's strike in Port Adelaide . In this case no shots were fired and the strikers did not confront the police or troops . Additional defence acts were passed in 1886 , 1890 and 1895 but , until defence passed into federal hands after 1901 , the state 's permanent military force was composed solely of artillery . Shortly after the federation of Australia , a regiment of the Royal Australian Artillery ( <unk> ) was formed and what had been the Permanent Artillery became <unk> company <unk> . The fort was manned to an extent during World War I , with one non @-@ commissioned officer and 11 gunners stationed as of November 1914 . Military reports and orders show the fort manned to at least mid @-@ 1918 , though at this point it is doubtful if the guns were fit to engage targets .
