The last five hours had been both nerve-racking and tiring work but as he had just spent the best part of five days either in bed or lying down he had plenty of reserves of energy, so he put his best foot forward and, taking a short rest every half-hour, passed group after group of wearily-plodding people. At about half-past three he came to a main crossroads right out in the open country and the signpost showed him that the road he had been on led to The Hook while that which cut into it from the north went to Delft.
Down this was trickling another stream of refugees and as the two streams mingled at the crossroads some groups took the road south while others went west towards The Hook. Under the signpost Gregory sat down to rest again and smoke a cigarette while he considered the situation.
He had long since given up any hope of getting through or round Rotterdam with a view to trying to cross the Dutch frontier into Belgium, and it was now quite clear that his only means of getting out of Holland was by sea. The question was which road offered him the best prospect? That to the south led to the broad mouth of the river, which was less than three miles away, and he might succeed in getting a small boat there at a village on the coast; but it was said that the Germans had mined the estuary, and there was no proper port along the shore where ships would be embarking refugees. On the other hand he was pretty tired now, The Hook was still seven miles distant and he had only his legs to carry him; but, unless the Germans had got there already, in the big harbour he was much more likely to find a ship that would take him to England. Grimly he decided to face the longer journey and stubbing out his cigarette stood up to tramp on again.
He spoke to nobody, for he felt that the Dutch must now have very good reason to suspect all foreigners of being Fifth Columnists, and he had no intention of risking being lynched, or arrested again and confined in another police-station while inquiries were being made about him. If he had not considered that discretion was so very necessary he might possibly have bought a lift for part of the way, as a number of cars and carts were constantly passing, but he preferred to make quite certain of retaining his liberty, so he did the whole distance on foot, arriving at The Hook at seven in the morning. Since leaving the Rotterdam Police Headquarters, some eleven hours earlier, he reckoned that he must have covered well over twenty miles and he was seriously feeling the effects of his exertions; but on entering the town he was immensely cheered by the sight of British sailors and marines.
They appeared to have taken charge of the traffic and the whole harbour area. Some were directing the stream of refugees towards the docks while others were carting ashore large cases, which Gregory guessed contained explosives. As he had been approaching the port he had heard several heavy detonations, but such sounds had become a normal background to his life during these past few days so, tired as he was, he had not taken any special notice of them, assuming that as German planes were once again circling overhead they were bombing the harbour; but he had hardly reached the docks when there was a terrific crash and a whole wharf about half a mile distant seemed to disintegrate in a sheet of blinding flame. The Navy knew their business and were seeing to it that there would not be much left in the way of harbour works by the time the Germans got there.
Good-humouredly, but firmly, the British sailors and marines herded the never-ceasing flow of refugees into the long customs sheds while Dutch interpreters who were working with them told the crowds of grimy, despondent people that they must abandon their cars, vans, wagons and all their contents as, in order that the ships which were leaving could take the maximum number of passengers, they could not be allowed to retain anything but hand luggage.
For over an hour Gregory waited in the customs shed, resting his weary limbs by lying at full length along one of the benches with his head pillowed on his arms. While he lay there further shocks more like earthquake tremors rocked the building and a number of lesser bumps together with anti-aircraft fire showed that the Nazi planes were strafing the refugees and their rescuers. From time to time batches of the patient, sad-eyed crowd were shepherded out on to the quayside, and at last came Gregory's turn to be taken on board a cargo vessel.
Now that he had a proper chance to look round he saw that one side of the fairway had already been blocked by the sinking of a dredger and two trawlers and that other vessels lying near by were evidently in readiness to be used for closing the gap, when the last evacuee ship had cleared the harbour mouth.
The great steel gates of an inner lock were half-submerged and twisted almost beyond recognition, and in many places fires were burning where the British had dynamited port-authority buildings and warehouses.
Every now and again waves of German bombers came over to add their quota to the racket but most of their bombs fell harmlessly in the sea. Once on board Gregory found himself a corner among the crowd where he could sit on the deck with his back to the engine-room hatch, and, like many others of the exhausted refugees who were past caring about the bombs, dropped off to sleep.
When he awoke he had the curious sensation that something strange was going on, but after a moment he realised that it was only the silence which seemed unnatural. The ship was out of sight of land and for the first time in six days the crash of bombs and the rumble of guns were no longer audible. He found that it was half-past two in the afternoon but it was not until eleven o'clock that night that they put into Harwich, and even then, in spite of his British passport and reiterated statements that he was not a refugee, he had to submit to a rigorous examination by the Security Police who were exercising every possible precaution to prevent German Fifth Columnists entering Britain with the genuine victims of Nazi persecution. It was past one before he was able to get away from his unfortunate fellow-travellers, who were being specially catered for, and nearly two when he flopped into bed at the Station Hotel.
He did not wake till ten o'clock on the Thursday morning but he had hardly opened his eyes before he recalled the urgent necessity of getting back to Brussels, and to Erika, now that the Blitzkrieg was on, without losing a moment. He knew, without inquiring, that all passenger sailings would have been cancelled, so he at once got on to London and was fortunate enough to catch Sir Pellinore at home.
Having told his elderly friend the gist of his news he asked if permission could be obtained for him to be taken on board any naval vessel which might be leaving Harwich for Belgian waters. Sir Pellinore said that he thought matters could be arranged and that he would get in touch with the Admiralty at once.
On reaching the hotel Gregory had been too utterly weary for more than a rough clean-up, so, having telephoned down for breakfast to be brought in half an hour, he lay for a bit in a hot bath, soaking off the rest of the smoke and grime of Rotterdam. His breakfast, which consisted of China tea, smoked haddock with a poached egg, and mushrooms on toast, was a special order given on his old principle that the best meal obtainable was never too good if there was no knowing when one was going to get another. When he had finished it he felt distinctly better and turned his attention to the morning papers.
