This chapter concerns four mutinies that occur against the background of revolutionary times, when the status quo is under threat, the military subordinates are no longer willing to acquiesce quietly, and the establishment is in a high state of nervous anxiety. The first two mutinies, at Spithead and the Nore in 1797, shook the British Royal Navy to its core: in the face of revolutionary acts across the channel in France, the seamen at Spithead effectively stop working until their claims of better pay and conditions are met. Given the precarious nature of the British Admiralty and government at this time, the mutiny is a success, but the consequences for a very similar mutiny just weeks later at the Nore are catastrophic for the mutineers as the British establishment unveils the mailed fist that it had been unable to deploy at Spithead. A few months later, in the same year, the crew of the Hermione undertake one of the bloodiest mutinies in British naval history, but one aimed at disposing of the officers and escaping to foreign lands, not securing improved pay and conditions. Some of the mutineers disappear for good, while others are hunted down and executed in a show of terror as meticulous as the original mutiny. The final mutiny covered here occurs on the Russian ship the Potemkin in 1905. Once again, the action occurs against the background of revolutionary fervour, but the requisite political support remains inadequate and the mutiny ultimately fails.
