In the wars

From Jasper Ridley's Palmerston:

Next day the newspapers confirmed the news of Waterloo...It was the last of the 182 engagements in which the British Army had fought since the first action at Valenciennes in July 1793. Palmerston, with his usual methodical habits, tabulated all the battles and losses sustained in each; in the twenty-one years of war, including the war against the United States of 1812-1814, the British Army had suffered a total of 920 officers and 15,214 other ranks killed, of whom nearly one-sixth had fallen in the last week in Belgium. In the Navy, the total losses were 3,662, the combined losses in both services of twenty-one years of war being less than one-third of the number who fell in one day's fighting at the Somme in 1916.
