allowed to take part in the negotiations, the German government issued a protest against what it considered to be unfair demands, and a "violation of honour", soon afterwards withdrawing from the proceedings of the peace conference. Germans of all political shades denounced the treaty—particularly the War Guilt Clause that blamed Germany for starting the war—as an insult to the nation's honour. They referred to the treaty as "the Diktat" since its terms were presented to Germany on a take-it-or-leave-it basis. Germany's first democratically elected head of government, Philipp Scheidemann, resigned rather than sign the treaty. In an emotional and polemical address to the Weimar National Assembly on 12 May 1919, he called the treaty a "horrific and murderous witch's hammer", and exclaimed: At the end of his speech, Scheidemann stated that, in the government's opinion, the treaty was unacceptable. After Scheidemann's resignation, a new coalition government was formed under Gustav Bauer. President Friedrich Ebert knew that Germany was in an impossible situation. Although he shared his countrymen's disgust with the treaty, he was sober enough to consider the possibility that the government would not be in a position to reject it. He believed that if Germany refused to sign the treaty, the Allies would invade Germany from the west—and there was no guarantee that the army would be able to make a stand in the event of an invasion. With this in mind, he asked Field Marshal Paul von Hindenburg if the army was capable of any meaningful resistance in the event the Allies resumed the war. If there was even the slightest chance that the army could hold out, Ebert intended to recommend against ratifying the treaty. Hindenburg—after prodding from his chief of staff, Wilhelm Groener—concluded the army could not resume the war even on a limited scale. But rather than inform Ebert himself, he had Groener inform the government that the army would be in an untenable position in the event of renewed hostilities. Upon receiving this, the new government recommended signing the treaty. The National Assembly voted in favour of signing the treaty by 237 to 138, with five abstentions (there were 421 delegates in total). This result was wired to Clemenceau just hours before the deadline. Foreign minister Hermann Müller and colonial minister Johannes Bell travelled to Versailles to sign the treaty on behalf of Germany. The treaty was signed on 28 June 1919 and ratified
