Note 102 — Chapter XI · —Arrangements made by Alexander for crossing the Hydaspês unobserved

“Arrian,” says Cunningham, “records that Alexander placed running sentries along the bank of the river at such distances that they could see each other and communicate his orders. Now, I believe that this operation could not be carried out in the face of an observant enemy along any part of the river bank, excepting only that one part which lies between Jalâlpûr and Dilâwar. In all other parts the west bank is open and exposed, but in this part alone the wooded and rocky hills slope down to the river and offer sufficient cover for the concealment of single sentries.”—Geog. of Anc. India, pp. 170, 171.
