I have mispronounced this word so many times.
Balaclavas and cardigans have more in common than keeping you warm—they both owe their names to the Crimean War. During the Battle of Balaclava in 1854, British troops were underprepared for the cold Ukrainian winter, and unlike their French counterparts, who were allowed to wear as many layers as required to stay warm, the British were expected to adhere to their uniforms. The poor conditions caused a scandal in Britain and motivated civilians to donate money and knit warm clothing for the troops using government-issued patterns and regulation yarn, including a wool cap to be worn under their helmets. The British referred to these caps as Balaclava helmets, and later just called them balaclavas. Troops were also issued button-down woolen jackets, which were named after the Lord of Cardigan, who led their ill-fated charge known as the Light Brigade against the Russians.
