LONDON--A squadron of German planes bombed British warships in the Firth of Forth at Edinburgh today, wounding 35 sailors and slightly damaging the cruiser Southampton before they were beaten off with at least four of the Nazi bombers shot down along the Scottish coast.

The German High Command announced in Berlin tonight that two British cruisers were hit by heavy-caliber bombs and that the German raiders and the British defense force each lost two planes.

The British Admiralty and Air Ministry admitted casualties aboard the 9,100-ton Southampton, the cruiser Edinburgh and the destroyer Mohawk, and said an admiral's barge and a light tender were sunk by the Nazi bombs.

The Nazi air-raiders--12 or 14 Heinkels and Dorniers--struck in a bold attempt to bomb Britain's Rosyth naval base and the huge bridge over the Firth of Forth nine miles inland from Edinburgh.

The German planes which escaped field out across the North Sea toward their German bases with British planes in machine-gunning pursuit.
