But Baird- Smith was not destined to spend his life making ditches. He saw service at Aliwal and Sobraon (1846), and at Chilianwalla and Gujerat (1848). In 1855 he returned to Madras to visit the chief irrigation works of the Presidency.
In 1857 Baird-Smith was at Roorkee, where, by his prompt action and quick foresight, he saved that station from an outbreak.

He started at once and arrived in camp early on the 3rd, but only to find that the assault had been postponed.' The post-ponement was a wise decision.
