There was no guarantee that these troops would remain in Australia if war broke out elsewhere and as a result, in 1869, in response to requests for assurances in this regard the British government announced that the capitation fee would be increased and that troop numbers would be further increased. Finally, in 1870 the decision was made to withdraw the remaining regiment and as a result, by September with the departure of the 18th (Royal Irish), the withdrawal of British forces from Australia was completed, except for a small number of Royal Marines who would remain in the country until 1913, and the local forces assumed total responsibility for the defence of the colonies. The influence of the British Army would continue to be felt, however, through fortifications and defences that were built and in the customs, traditions, uniforms, heraldry and organisational structure that developed in the colonial forces and which, through these links, have been maintained in the modern incarnation of the Australian Army.
