During the rains of fall, and when summer bursts upon winter, in June, is the season of _rasputitsa_. The wagon roads then are sloughs of deep mire, and little travel is attempted. The first snow falls in November and gradually mounts, until in January it has a uniform height of three feet, except in the open places where there are great drifts much higher. No thaw comes until late February, and so moving for any distance on foot is impossible without skis or snowshoes. Cold follows the snow, gradually increasing in intensity until there are January days of forty-five and fifty degrees below zero Fahrenheit. When the wind is high and the air filled with great, white blasts, this cold of Russia presses on the diaphragm like a ponderous weight and breathing becomes a gasping effort. In the depth of winter, the sun is banished, and during the latter part of December, only a few hours of pale, anemic glimmering separates the black Arctic night; a shadowy gloaming, like shortlived, desert twilight. Splendid, fighting men were made weak cowards by the cumulative depression of the unbroken, Russian night and its crushing influence on the spirit; for the severest battles of the campaign were fought during the cold, black months of winter time. Preparations for opening hostilities in the war with Russia were made in April, 1918. The Allied Supreme War Council had been alert to the presence of German troops in Finland and their fanciful menace to the Murman railway; and in the quiet harbor of Murmansk, British and French battleships had been idling purposelessly since early spring. In April, one hundred fifty Royal Marines landed from the British ships and were followed in a few weeks by four hundred more, also a landing party of French sailors. On 10th June, the United States warship, _Olympia_, appeared at Murmansk, and one hundred American bluejackets disembarked. These Allied forces penetrated down the Murman railway to Klandalaksh, some two hundred fifty miles south, and, in addition to holding Murmansk, seized the port of Petchenga on the coast of Finland. Then the scene of intervention shifted southward, and on the 1st August, General Poole, with a party of five hundred fifty French, British and a few American marines, escorted by a British cruiser, a French cruiser and a trawler fleet, attacked Archangel, which, after a bombardment, was surrendered next day by the weak Bolshevik rear guard.
