Bernave's inability to build a consensus in the Assembly resulted in the appointment of a new government, chiefly composed of "Brissotins". On 20 April 1792 the French Revolutionary Wars began when France armies attacked Austrian and Prussian forces along their borders, before suffering a series of disastrous defeats. In an effort to mobilise popular support, the government ordered non-juring priests to swear the oath or be deported, dissolved the Constitutional Guard and replaced it with 20,000 "fédérés"; Louis agreed to disband the Guard, but vetoed the other two proposals, while Lafayette called on the Assembly to suppress the clubs.
