Three seconds had elapsed since the violet-gray cloud of fury struck the town, but in those three seconds 30,000 people lay dead, slain with such appalling swiftness that none knew their fate. No one had tried to escape.
The eruption was witnessed, from a distance, by only one trained observer, Roger Arnoux, and a translation of his record is, in part, as follows:
"Having left St. Pierre at about five in the evening (May 7) I was witness to the following spectacle: Enormous rocks, being clearly distinguishable, were being projected from the crater to a considerable elevation, so high, indeed, as to occupy a quarter of a minute in their flight.
"About eight o'clock of the evening we recognized for the first time, playing about the crater, fixed fires that burned with a brilliant white flame. Shortly afterwards, several detonations, similar to those that had been heard at St. Pierre, were noted coming from the south, which confirmed me in my opinion that there already existed a number of submarine craters from which gases were being projected, to explode when coming in contact with the air.
"Having retired for the night, at about nine o'clock, I awoke shortly afterwards in the midst of a suffocating heat and completely bathed in perspiration.... I awoke again about eleven thirty-five, having felt a trembling of the earth ... but again went to sleep, waking at half-past seven. My first observation was of the crater, which I found sufficiently calm, the vapors being chased swiftly under pressure of an east wind.
"At about eight o'clock, when still watching the crater (M. Arnoux was the only man who saw the beginning of the eruption and lived to tell the tale), I noted a small cloud pass out, followed two seconds after by a considerable cloud, whose flight to the Pointe de Carbet (beyond the city) occupied less than three seconds, being at the same time already in our zenith, thus showing that it developed almost as rapidly in height as in length. The vapors were of a violet-gray color and seemingly very dense, for, although endowed with an almost inconceivably powerful ascensive force, they retained to the zenith their rounded summits. Innumerable electric scintillations played through the chaos of vapors, at the same time that the ears were deafened by a frightful fracas.
"I had, at this time, an impression that St. Pierre had been destroyed.... As the monster seemed to near us, my people, panic-stricken, ran to a neighboring hillock that dominated the house, begging me to do the same.... Hardly had we arrived at the summit when the sun was completely veiled, and in its place came almost complete blackness.... At this time we observed over St. Pierre, a column of fire, estimated to be 1,200 feet in height, which seemed to be endowed with the movement of rotation as well as onward movement." St. Pierre was no more.
Rescuers were soon on their way. Twenty-three minutes after the clouds had been seen rising from Mont Pelée and the cable and telephone lines were broken, a little steamer left Fort-de-France, the capital. It reached half-way, then, finding that the rain of stones and ashes threatened to sink it, returned. The boat started anew at ten o'clock and rounded the point of Carbet. The volcano was shrouded in smoke and ashes. For three miles the coast was in flames. Seventeen vessels in the roadstead, two of which were American steamers, burned at anchor. The heat from this immense conflagration prevented the boat from proceeding and it returned to Fort-de-France, reaching there at one o'clock, bringing the sinister tidings.
At midday, the Acting Governor of Martinique ordered the Suchet to go with troops to be under the direction of the Governor, then at St. Pierre. About three o'clock, a party was landed on the shore. The pier was covered with bodies. The town was all in fire and in ruins. The heat was such that the landing party could not endure more than three or four minutes. The Governor was dead also.
"St. Pierre," writes a witness on another rescue ship, which arrived at almost the same moment, "is no more. Its ruins stretch before us, in their shroud of smoke and ashes, gloomy and silent, a city of the dead. Our eyes seek the inhabitants fleeing distracted, or returning to look for the dead. Nothing to be seen. No living soul appears in this desert of desolation, encompassed by appalling silence.... Through the clouds of ashes and of smoke diffused in our atmosphere, the sun breaks wan and dim, as it is never seen in our skies, and throws over the whole picture a sinister light, suggestive of a world beyond the grave."
