The gate-way of the north side, from whence the garrison got their water, was near the N. W. angle, and about 80 yard from the river; on the side of which, opposite to the gate, they threw up a retrenchment, in which they kept a guard to protect the water-carriers. Lieutenant Rumbold, with the Europeans, passed the river under cover of a field-piece, and having dislodged the guard from the post on the other side, kept possession, strengthened it with better retrenchments, and stationed two companies of Sepoys to maintain it.
