Thanks ORAC - the links to the Hindu - most useful - a map (a terrible map) but a map at last - and quite a balanced account.
What seems to be clear is that is the Chinese haven't provided a map of where they think the actual line runs - which is not good. It allows them to claim all sorts of infringements that no-one else has any idea about.
For those interested the actual position of the action seems to be around 34 deg 45' 30"N 078 deg 11' 04" E - on GE the LAC (in red ) is well south of the Galwan (or Gallowan on GE) river until it get close near to the subsidiary river coming in from the south 5km upstream from the Shyock/Galwan junction where is apparently a long established Chinese border marker. What seems to kicked things of was the completion of a bridge - but not sure if that was over the Galwan (bridge N_S) or and E-W bridge over the Shyok linking the finger of the Indian area to the main areas to the west. Chinese trying to push west to be able to overlook the strategic road that runs N-S on the west side of the Shyock
