Warsaw From Air Sad Sight With Palace, City In Ruins By MELVIN WHITELEATHER WARSAW, Sept. 30. Warsaw is in ruins. There is scarcely an undamaged building in the center of the Polish capital. The former Saxon palace on spacious Pilsudski square in the heart of the city, which housed the Polish foreign office has been shelled and burned. Other buildings in the vicinity of the square suffered equally from shells and bombs. The citys two largest hotels are located there. I circled twice tonight in a Junkers plane over the city whose roof was ripped open to tha sky during the 20 day siege by German armies. It was a sad sight, first in the late afternoon and then at dusk as a red moon peered over the horizon casting a glow on the Vistula river. At least a hundred fires were burning. Bitter fighting took place in Praga before the capital was shelled heavily and tonight it was a trench town. Trenches zig zagged along the streets and back yards. They even were dug in front of apartment house doors so it was possible to step from the front door into a trench. A long line of bedraggled Polish soldiers, unarmed, marched in good order westward out of the city. They had stacked their guns. The first group of thousands of Polish soldiers, who held the city until it was battered to pieces and forced to surrender Sept. 27, left last night. The last are due to depart Sunday night. Outside the city they are met by Germans and taken prisoner. German troops are scheduled to occupy the city Oct. 2.
