What is the fate of the Martian fleet after the Astronef's encounter?

After the Astronef's encounter with the Martian fleet, Lord Redgrave retaliated against their hostile actions^[1]. He rammed one Martian air-ship, causing it to break in two and plunge downwards through the clouds^[1]. He also used an explosive shell, 'Rennickite,' to destroy another air-ship, leaving only a deep, red, jagged gash in the ground^[1].

The Astronef then dropped onto the largest Martian air-ship, smashing it to fragments^[1]. Following these attacks, the remaining Martian fleet scattered in all directions, sinking rapidly down through the clouds^[1].
