The war took its toll on the Percheron breed as horses, fodder, and handlers were requisitioned for the fighting, and even after the embargo was lifted France did not have the quality or quantity of stock to fulfill the needs of American breeders. The embargo created a breeding boom in the US, replacing the previous practice of importing the majority of Percherons from France, and late in the war horses were shipped the other way – from the US to Europe – to supply those needed in the war.[22] The lack of feathering on the Percheron's lower legs made them easier to care for in the mud that they often worked in during wartime. Their quick trot on paved roads made them more versatile than motorized vehicles, and they were useful for work with guns and in forward units due to their calm temperaments.[3]
