The support of the Legion was taken care of by the Serbian government. The members had to go through some military training so as to be able to participate in the future uprising and in the expected conflict between Serbia and the Ottoman Empire. According to Trotsky, when the Turkish forces entered Belgrade, the Bulgarian legion distinguished itself in the fighting. However the conflict ended swiftly and the subsequent Constantinople Conference decided that not all Ottoman troops should withdraw from Serbia. Due to pressure from the Ottoman Empire the Serbian authorities requested the Legion to be disbanded. As a result, on 21 September 1862 the participants were expelled from Belgrade.
