Thus in essence the Dutch 'position' in Sumatra insofar as they had one could have been undone by the British with relative ease. It was undone on a few occasions notably when the British response to a proposed Dutch invasion of Aceh in the 1860s came back less than enthusiastic, so much so that the British in effect stated quite unequivocally that they wouldn't condone such an action because it would have proved detrimental to British interests. This placed the Dutch in a position where they couldn't react to Acehnese provocations, without fear of pissing the British off. The net result of which was that the Acehnese bought themselves twenty more years, and the Dutch were forced to abandon a substantial number of clients to placate British interests. The 1824 Treaty such as it was wasn't worth the paper it was written on while the pepper trade was important to British merchantile interests
