Silk tells Savage that he has a surprise waiting for him when they return to their base. The surprise is a Royal Navy Underwater team. They have scuba gear and limpet mines and they're going to blow The Volga out of the water.
Silk was an ex-army officer and he was trained in underwater demolition. He tells Savage that he can't join the party because he doesn't have the necessary skills.
Later, at the docks, with The Volga approaching, Silk and his team dive into the water. Savage watches from a distance. He has a plan just in case Silk and his crew fail to sink the ship.
As Silk and his frogmen approach the Volga, the Admiral onboard has been informed that six frogmen are approaching their vessel. He gives the order to use the ships sonic weapons.
Silk is the only survivor. He is taken onboard the ship for interrogation. After witnessing Silks failure, Savage executes his own plan. Using the cranes on the docks...Savage and his men swing into action. As Savage sweeps the deck clear of Volgans. The Admiral makes himself scarce and hids below deck. Savage swings aboard his special cargo...oil! This should take care of everything. Savage orders his men off the ship and he ignites the oil. Mission accomplished!
Fairly run-of-the-mill Invasion story. Nothing much to say here. Although the Bil Savage saying 'Hello Sailor...' is all kinds of disturbing!
The art by Carlos Pino is serviceable but kind of forgettable.
