Three weeks later, Sumbhajee's fleet of five grabs and some gallivats appeared off Bombay, and cruised off the mouth of the harbour, as if inviting attack. Commodore Langworth, with the _Pulteney_, _Trial, _Neptune's Prize_, a bombketch, and five of the largest gallivats, was sent out. The Angrian fleet stood away to the southward, followed by Langworth. The demonstration was a trick to draw off the Bombay fighting ships. When they were well out of the way, Sumbhajee made a sudden attack on Mannajee's territories with two thousand men and forty or fifty gallivats. Sumbhajee had gained over a number of Mannajee's officers, and Alibagh, Thull, and Sagurgurh fell into his hands at once. He attacked Chaul, but was beaten off by the Portuguese, and then laid siege to Colaba. Mannajee was at once reduced to great straits. Half his garrison were untrustworthy, and his water supply was cut off. In his distress he appealed to Bombay for assistance. Though the Council bore him little good will, they recognized that it was better to maintain him in Colaba than to allow Sumbhajee to establish himself there; so, in great haste, the _Halifax_, a small country ship, the _Futteh Dowlet_ grab, the _Triumph_, _Prahm_, and the _Robert_ galley were equipped and sent down, under Captain Inchbird, arriving just in time to save the place. Water was supplied to the garrison, and Bombardier Smith, together with gunner's mate Watson, a mortar and plenty of ammunition were put into the fort. Sumbhajee's batteries were much damaged by the shells from the mortar, his camp was bombarded by Inchbird, and his gallivats forced to run for Severndroog. This prompt action of the Bombay Council upset Sumbhajee's plans. He addressed remonstrances to the Council, offering to restore the _Anne_, which he had taken some months before. A week later, a Mahratta force, from Salsette, under the Peishwa's son, Ballajee Bajee Rao, appeared on the scene, attacked Sumbhajee's camp, destroyed some of his batteries, killing a number of his men, and taking prisoner his half-brother, Toolajee.
In his distress, Sumbhajee tried to come to terms with Mannajee. Each distrusted the other, and both were afraid of the Peishwa. At this juncture the death of the Peishwa was announced. Ballajee Bajee Rao was obliged to return to Satara, and Sumbhajee was allowed to retreat, after making peace with the Mahrattas. The promptitude and energy with which the English had come to the assistance of Mannajee raised them greatly in the esteem of the new Peishwa, and strengthened the bonds of the alliance.
