There have 'been rumours of fighting . in Poland, most of
which want confirmation. In the private correspondence of the Times to-day, a letter from Berlin, of the 25th April, mentions an obstinate and bloody affair between SIERA.WSKI and General WITT'S corps near Belzyce. The Poles, who were greatly out- numbered, were compelled to retreat, with a loss of 1,200 men. The Russians lost above 800 killed. DWERNICKI is still going on successfully ; but his ,exploits, though brilliant, serve rather to keep up the spirit of his countrymen, than to put down their for- midable enemy.
