Germany code-named the attack “Operation Sealion”. Most of the British Army's heavy weapons and supplies had been lost when it evacuated from Dunkirk, so the army was fairly weak. The previous text is in English. Here is a translation to Chinese (Traditional):
德國給那次攻擊取了「海獅計畫」的代號。英國軍隊從敦克爾克撤退時，大多數的重型武器和補給品都沒了，所以那時的英軍相當虛弱。
