A sense of common danger made Ledru-Rollin and Louis Blanc unite with their colleagues in refusing the demand of the deputation that the measures they advocated should be put in force by immediate decrees.  Lamartine harangued them; so did Ledru-Rollin and Louis Blanc; and at last the disappointed multitude, with vengeance in their hearts, filed peaceably away.

A month later, April 15, another outbreak was planned.  The chief club leaders wished it to be headed by Ledru-Rollin and Blanqui,—­the latter a conspirator in Louis Philippe’s time.  But Ledru-Rollin refused to serve with Blanqui, having discovered from documents in his office (that of Minister of Justice) that Blanqui had once been a Government spy.  “Well, then,” said the club leaders, “since you decline to be our chief, you shall to-morrow share the fate of your colleagues.”  Ledru-Rollin, after a terrible night of vacillation, resolved to throw himself on Lamartine’s generosity.  He went to him at daybreak and told him of the impending danger.  At once Lamartine sent him to call out the National Guard, while he himself summoned the Garde Mobile.  The National Guard had been reorganized; but there were no regular soldiers in Paris,—­they had been sent away to satisfy the people.  The commander of the National Guard, however, refused to let his men be called out on the occasion; and Lamartine, on hearing this, went to the Hotel-de-Ville alone.  But help came to him from an unexpected quarter.  General Changarnier, who had been appointed ambassador to Berlin, called at Lamartine’s house to return thanks for his appointment.  Madame de Lamartine told him of the danger that menaced her husband, and he repaired at once to the Hotel-de-Ville.  There he found only about twelve hundred boys of the Garde Mobile to oppose the expected two hundred thousand insurgents.  He drew his Garde Mobile into the building, and prepared to stand a siege.  There from early morning till the next day Lamartine remained with Marrast, the Mayor of Paris.  He says that he harangued the mob from thirty to forty times.  The other members of the Government remained in one of the public offices.  With much difficulty the National Guard, whose organization was not yet complete, was brought upon the scene.  The procession of the insurgents was cut in two, the commander of the National Guard employing the same tactics as those which the Duke of Wellington had used a week earlier, when dealing in London with the Chartist procession.  The result was the complete discomfiture of the insurgents.

A few days afterwards the members of the Provisional Government sat twelve hours, on thrones erected for them under the Arch of Triumph, to see Gardes Mobiles, National Guards, troops of the line, and armed workmen, file past them, all shouting for Lamartine and Order!  It was probably the proudest moment of Lamartine’s life; in that flood-tide of his popularity he easily could have seized supreme power.
