I saw through the periscope a Jap destroyer escort, a tanker, and a minelayer.

我通过潜望镜看到了一艘日本驱逐舰护航舰、一艘油轮和一艘布雷舰。

For fifteen hours, that Jap minelayer kept dropping depth charges.

十五个小时以来，那个日本布雷艇一直在投下深水炸弹。

Apparently the Jap minelayer had exhausted its supply of depth charges, and steamed away.

显然，日本布雷舰已经耗尽了它的深水炸弹供应， 然后离开了。

We were getting ready to attack the last ship, the minelayer, when suddenly she turned and came directly at us.

我们正准备攻击最后一艘船， 布雷舰，突然她转身直接向我们走来。

(A Jap plane had spotted us under sixty feet of water and had radioed our position to the Jap minelayer.) We went down to 150 feet, to avoid detection, and rigged for a depth charge.

（一架日本飞机在 60 英尺深的水下发现了我们， 并通过无线电将我们的位置报告给了日本布雷舰。）我们下降到 150 英尺， 以避免被发现， 并安装了深水炸弹。
