Each of the Hardy Group's Liberty ships was equipped with weapons, with heavy machine guns and rocket launchers being the standard equipment. Installing cannons would have been too conspicuous, so they opted to store several M-2 heavy mortars on board instead to deal with potential emergencies.
The theoretical range of the M-2 mortar is about 4 kilometers.
Once the personnel boarded, the ships set off immediately. They were in Hong Kong, while their target was in Shanghai, which was closer to the Taiwan than they were. If they couldn't get ahead of their target, they would miss out on everything. So as soon as they hit the open sea, all four ships sped forward at full throttle.
Two hours later.
Mr. Xu came to deliver information.
