By the middle of May the national deputies summoned at Lyons began to arrive. They were to meet, after the fashion of Charles the Great's assemblies, in the open field. Their task was to be the making of a new constitution. It was not reassuring news that they brought from their various homes, and their accounts disturbed public opinion in Paris sadly. Before long it was known that civil war had again broken out in Vendee; the consequences would have been most disastrous had not La Rochejacquelein, the insurgent leader, been killed on June fourth. As it was, the ignoble slaughter of one of their order intensified the bitterness of the nobles. Worse still, it had been found that of the six hundred and twenty-nine deputies five hundred were ardent constitutionalists indifferent to Napoleon, and that only fifty were his devoted personal friends; there were even between thirty and forty who were Jacobins, and at Fouche's command. Under these circumstances the Emperor dared not hold the promised national congress. What could be substituted for it? The great dramatic artist was not long at a loss. He determined to summon the electoral deputies to a gorgeous open-air ceremony on June first, and have them stamp with their approval the Additional Act. A truly impressive spectacle would pass muster for the promised "field of May," and profoundly affect the minds of all present. But, unfortunately, though Segur made the plan, and though every detail was carefully studied by Napoleon, the affair was not impressive. About eighteen thousand persons assembled on the benches, and there was a vast crowd in the field. The cannon roared their welcome, and the people cheered the imperial carriage, the marshals, the body-guard, and the procession. But when Napoleon and his brothers stepped forth, clad like actors in theatrical costumes of white velvet, wearing Spanish cloaks embroidered with the imperial device of golden bees, and with great plumed hats on their heads, there was a hush of disappointment. The populace had expected a soldier in a soldier's uniform; many had felt sure "he" would wear that of the National Guard.
